Oxidative refolding of recombinant prochymosin. (1/91)

The disulphide-coupled refolding of recombinant prochymosin from Escherichia coli inclusion bodies was investigated. Prochymosin solubilized from inclusion bodies is endowed with free thiol groups and disulphide bonds. This partially reduced form undergoes renaturation more efficiently than the fully reduced form, suggesting that some native structural elements existing in inclusion bodies and remaining after denaturation function as nuclei to initiate correct refolding. This assumption is supported by the finding that in the solubilized prochymosin molecule the cysteine residues located in the N-terminal domain of the protein are not incorrectly paired with the other cysteines in the C-terminal domain. Addition of GSH/GSSG into the refolding system facilitates disulphide rearrangement and thus enhances renaturation, especially for the fully reduced prochymosin. Based on the results described in this and previous papers [Tang, Zhang and Yang (1994) Biochem. J. 301, 17-20], a model to depict the refolding process of prochymosin is proposed. Briefly, the refolding process of prochymosin consists of two stages: the formation and rearrangement of disulphide bonds occurs at the first stage in a pH11 buffer, whereas the formation and adjustment of tertiary structure leading to the native conformation takes place at the second stage at pH8. The pH11 conditions help polypeptides to refold in such a way as to favour the formation of native disulphide bonds. Disulphide rearrangement, the rate-limiting step during refolding, can be achieved by thiol/disulphide exchange initiated by free thiol groups present in the prochymosin polypeptide, GSH/GSSG or protein disulphide isomerase.  (+info)

New world monkey pepsinogens A and C, and prochymosins. Purification, characterization of enzymatic properties, cDNA cloning, and molecular evolution. (2/91)

Pepsinogens A and C, and prochymosin were purified from four species of adult New World monkeys, namely, common marmoset (Callithrix jacchus), cotton-top tamarin (Saguinus oedipus), squirrel monkey (Saimiri sciureus), and capuchin monkey (Cebus apella). The occurrence of prochymosin was quite unique since this zymogen is known to be neonate-specific and, in primates, it has been thought that the prochymosin gene is not functional. No multiple form has been detected for any type of pepsinogen except that two pepsinogen-A isozymogens were identified in capuchin monkey. Pepsins A and C, and chymosin hydrolyzed hemoglobin optimally at pH 2-2.5 with maximal activities of about 20, 30, and 15 units/mg protein. Pepsins A were inhibited in the presence of an equimolar amount of pepstatin, and chymosins and pepsins C needed 5- and 100-fold molar excesses of pepstatin for complete inhibition, respectively. Hydrolysis of insulin B chain occurred first at the Leu15-Tyr16 bond in the case of pepsins A and chymosins, and at either the Leu15-Tyr16 or Tyr16-Leu17 bond in the case of pepsins C. The presence of different types of pepsins might be advantageous to New World monkeys for the efficient digestion of a variety of foods. Molecular cloning of cDNAs for three types of pepsinogens from common marmoset was achieved. A phylogenetic tree of pepsinogens based on the nucleotide sequence showed that common marmoset diverged from the ancestral primate about 40 million years ago.  (+info)

A basic residue at position 36p of the propeptide is not essential for the correct folding and subsequent autocatalytic activation of prochymosin. (3/91)

Position 36p in the propeptides of gastric aspartic proteinases is generally occupied by lysine or arginine. This has led to the conclusion that a basic residue at this position, which interacts with the active-site aspartates, is essential for folding and activation of the zymogen. Lamb prochymosin has been shown by cDNA cloning to possess glutamic acid at 36p. To investigate the effect of this natural mutation which appears to contradict the proposed role of this residue, calf and lamb prochymosins and their two reciprocal mutants, K36pE and E36pK, respectively, were expressed in Escherichia coli, refolded in vitro, and autoactivated at pH 2 and 4.7. All four zymogens could be activated to active chymosin and, at both pH values, the two proteins with Glu36p showed higher activation rates than the two Lys36p forms. Glu36p was also demonstrated in natural prochymosin isolated from the fourth stomach of lamb, as well as being encoded in the genomes of sheep, goat and mouflon, which belong to the subfamily Caprinae. A conserved basic residue at position 36p of prochymosin is thus not obligatory for its folding or autocatalytic activation. The apparently contradictory results for porcine pepsinogen A [Richter, C., Tanaka, T., Koseki, T. & Yada, R.Y. (1999) Eur. J. Biochem. 261, 746-752] can be reconciled with those for prochymosin. Lys/Arg36p is involved in stabilizing the propeptide-enzyme interaction, along with residues nearer the N-terminus of the propeptide, the sequence of which varies between species. The relative contribution of residue 36p to stability differs between pepsinogen and prochymosin, being larger in the former.  (+info)

Cathepsin D isozymes from porcine spleens. Large scale purification and polypeptide chain arrangements. (4/91)

Six cathepsin D isozymes have been purified from porcine spleen using a large scale purification procedure. Five isozymes, I to V, have an identical molecular weight of 50,000 and are similar in specific activity. Isozymes I to IV contained two polypeptide chains each. The light and heavy chains have Mr = 15,000 and 35,000, respectively. Isozyme V is a single polypeptide. The molecular weight of the sixth isozyme is about 100,000 and it has only 5% of the specific activity of the other isozymes. On Ouchterlony immunodiffusion, an antiserum formed precipitin lines against the urea-denatured isozyme with Mr = 100,000. This immunoreactivity showed immunoidentity with those formed against other isozymes. The NH2-terminal sequence of light chains was identical for the isozymes. This sequence is homologous to the NH2-terminal sequence of other acid proteases, especially near the region of the active center aspartate-32. The NH2-terminal sequence of the single chain, isozyme V, Is apparently the same as the light chain sequence. The NH2-terminal sequence analysis of the heavy chain from isozyme I produced two sets of related sequences, suggesting the prescene of structural microheterogeneity. The carbohydrate analysis of the isozymes, the light chain, and the heavy chain revealed the presence of possibly four attachment sites, with one in the light chain and three in the heavy chain. Each carbohydrate unit contains 2 residues of mannose and 1 residue of glucosamine. The results suggest that the high molecular weight cathepsin D (Mr = 100,000) is the probable precursor of the single chain (Mr = 50,000), which in turn produces the two-chain isozymes. These are likely in vivo processes.  (+info)

Precise and efficient cleavage of recombinant fusion proteins using mammalian aspartic proteases. (5/91)

Expression of recombinant proteins as translational fusions is commonly employed to enhance stability, increase solubility and facilitate purification of the desired protein. In general, such fusion proteins must be cleaved to release the mature protein in its native form. The usefulness of the procedure depends on the efficiency and precision of cleavage and its cost per unit activity. We report here the development of a general procedure for precise and highly efficient cleavage of recombinant fusion proteins using the protease chymosin. DNA encoding a modified pro-peptide from bovine chymosin was fused upstream of hirudin, carp growth hormone, thioredoxin and cystatin coding sequences and expressed in a bacterial Escherichia coli host. Each of the resulting fusion proteins was efficiently cleaved at the junction between the pro-peptide and the desired protein by the addition of chymosin, as determined by activity, N-terminal sequencing and mass spectrometry of the recovered protein. The system was tested further by cleavage of two fusion proteins, cystatin and thioredoxin, sequestered on oilbody particles obtained from transgenic Arabidopsis seeds. Even when the fusion protein was sequestered and immobilized on oilbodies, precise and efficient cleavage was obtained. The precision, efficiency and low cost of this procedure suggest that it could be used in larger scale manufacturing of recombinant proteins which benefit from expression as fusions in their host organism.  (+info)

Improvement of foreign-protein production in Aspergillus niger var. awamori by constitutive induction of the unfolded-protein response. (6/91)

Unfolded-protein response (UPR) denotes the upregulation of endoplasmic reticulum (ER)-resident chaperone and foldase genes and numerous other genes involved in secretory functions during the accumulation of unfolded proteins into the ER. Overexpression of individual foldases and chaperones has been used in attempts to improve protein production in different production systems. We describe here a novel strategy to improve foreign-protein production. We show that the constitutive induction of the UPR pathway in Aspergillus niger var. awamori can be achieved by expressing the activated form of the transcription factor hacA. This induction enhances the production of Trametes versicolor laccase by up to sevenfold and of bovine preprochymosin by up to 2.8-fold in this biotechnically important fungus. The regulatory range of UPR was studied by analyzing the mRNA levels of novel A. niger var. awamori genes involved in different secretory functions. This revealed both similarities and differences to corresponding studies in Saccharomyces cerevisiae.  (+info)

Calf chymosin as a catalyst of peptide synthesis. (7/91)

Calf chymosin was shown to catalyse peptide synthesis optimally over the range pH 4-5, giving satisfactory yields of methyl esters or p-nitroanilides of benzyloxycarbonyl tetra- to hexa-peptides, provided that hydrophobic amino-acid residues form the new peptide bonds. The effectiveness of the enzyme depends also on the nature of adjacent amino-acid residues. As an aspartate-proteinase with a characteristic specificity pattern chymosin would be useful for the synthesis of middle-length peptides.  (+info)

Characterization and study of a kappa-casein-like chymosin-sensitive linkage. (8/91)

The present report is dealing with the identification, in various unrelated proteins, of protein fragments sharing local sequence and structure similarities with the chymosin-sensitive linkage surrounding the Phe-Met/Ile bond of kappa-caseins. In all these proteins, this linkage is observed within an exposed beta-strand-like structure, as also predicted for kappa-caseins. The structure of one of these fragments, included in glutamine synthetase, particularly superimposes well with the conformation observed for a chymosin inhibitor (CP-113972) within the complex it forms with chymosin and can be similarly accommodated by specificity pockets within the enzyme substrate binding cleft. The effect of the enzyme activity of chymosin was thus tested on glutamine synthetase. Chymosin cut the latter at the Phe-Met linkage, suggesting that this system may locally resemble the kappa-casein/chymosin complex.  (+info)

Bovine and camel chymosin are aspartic peptidases that are used industrially in cheese production. They cleave the Phe105-Met106 bond of the milk protein κ-casein, releasing its predominantly negatively charged C-terminus, which leads to the separation of the milk into curds and whey. Despite having 85% sequence identity, camel chymosin shows a 70% higher milk-clotting activity than bovine chymosin towards bovine milk. The activities, structures, thermal stabilities and glycosylation patterns of bovine and camel chymosin obtained by fermentation in Aspergillus niger have been examined. Different variants of the enzymes were isolated by hydrophobic interaction chromatography and showed variations in their glycosylation, N-terminal sequences and activities. Glycosylation at Asn291 and the loss of the first three residues of camel chymosin significantly decreased its activity. Thermal differential scanning calorimetry revealed a slightly higher thermal stability of camel chymosin compared with ...
Chymosin (Rennin EC 3.4.23.4), an aspartyl proteinase, is the major proteolytic enzyme in the fourthstomach of the unweaned calf, and it is formed by proteolytic activation of its zymogene, prochymosin.Following the cloning of synthesized cDNAs on mRNA pools extracted from the mucosa of the calf fourthstomach, we have identified an alternatively spliced form of preprochymosin cDNA (AS6 preprochymosin).Sequencing data analysis showed that the exon six has been spliced out and, therefore the gene productis 114 bp shorter in length. In order to determine the biological significance of the AS6 preprochymosin, weexpressed the encoding cDNA together with a complete chymosin cDNA in E. coli. Under the same expression conditions, we found at least a 5-fold higher expression of AS6 preprochymosin protein in comparisonto a full-length recombinant chymosin. Protein prediction program analyses showed that the missingexon contain groups of amino acids with high hydrophobicity score. Therefore, the deletion of this
Chymosin /ˈkaɪməsɪn/ or rennin /ˈrɛnɪn/ is a protease found in rennet. It is an aspartic endopeptidase belonging to MEROPS A1 family. It is produced by newborn ruminant animals in the lining of the abomasum to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption. It is widely used in the production of cheese. Bovine chymosin is now produced recombinantly in E. coli, Aspergillus niger var awamori, and K. lactis as alternative resource. Chymosin is produced by ruminant animals in the lining of the abomasum. Chymosin is produced by gastric chief cells in young ruminants and some other newborn animals to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption. Some other non-ruminant species, including pigs, cats, and seals, produce it. One study reported finding a chymosin-like enzyme in some human infants, but others have failed to replicate this finding. Humans have a pseudogene for chymosin that does not generate ...
Cheese from donkey milk was never produced by traditional way. Research suggests that asinine milk by bovine chymosin form a very weak gel compared to the gel formed from bovine milk and with out curd formation.  Encyclopedia of Dairy Sciences 2nd edition reported that no cheese is made from donkey milk, due to its particular caseinic composition that makes inefficient the traditional rennet coagulation. However, the author has recently discovered that pure camel chymosin is able to clot effectively the casein micelles of donkey milk. This investigation is aimed at experimental manufacturing of donkey cheese through pure camel chymosin. A total of five experiments were included in the present investigation. Before making cheese, the raw donkey milk samples were analyzed for their physico-chemical composition in order to better evaluate the successive properties of fresh donkey cheese. Cheese making using pure camel chymosin gave a yield of about 3.32% of fresh donkey cheese, however relative to

This the rennet used in most traditional cheese making plants. The rennet or rennin refers to collection of enzymes that comes from the fourth stomach of ruminant animals (kid, calf or lamb). If we look at rennet through a chemists eyes, rennet is chiefly made up of two enzymes that break down protein chains in milk: chymosin and pepsin. The enzyme mostly responsible for coagulating milk is chymosin as it works to breakdown casein-the primary protein of concern to cheesemakers. As chymosin is the chief coagulating agent, today we see highly clarified versions of animal rennets which contain up to 97% chymosin-an outcome considered to be desirable by some cheese makers hoping to achieve a very clean taste profile and quick set. In addition, there are now also organic animal rennets on the market. Animal rennet in any form is still the most expensive coagulant (Up to 2x more expensive than alternatives) on the market. Its price is a function of supply which in turn is tied to events on the ...

The secretion of heterologous animal proteins in filamentous fungi is usually limited by bottlenecks in the vesicle-mediated secretory pathway. Using the secretion of bovine chymosin in Aspergillus awamori as a model, we found a drastic increase (40 to 80-fold) in cells grown with casein or casein phosphopeptides (CPPs). CPPs are rich in phosphoserine, but phosphoserine itself did not increase the secretion of chymosin. The stimulatory effect is reduced about 50% using partially dephosphorylated casein and is not exerted by casamino acids. The phosphopeptides effect was not exerted at transcriptional level, but instead, it was clearly observed on the secretion of chymosin by immunodetection analysis. Proteomics studies revealed very interesting metabolic changes in response to phosphopeptides supplementation. The oxidative metabolism was reduced, since enzymes involved in fermentative processes were overrepresented. An oxygen-binding hemoglobin-like protein was overrepresented in the proteome following

3CMS: Engineering enzyme subsite specificity: preparation, kinetic characterization, and X-ray analysis at 2.0-A resolution of Val111Phe site-mutated calf chymosin.
A study was made of the action of the enzyme rennin on β-casein. Hydrolysis of β-casein initially at a single sensitive bond under controlled conditions of temperature, pH and relative enzyme and substrate concentrations, formed the basis of the investigation. Information on the hydrolysis of this sensitive bond was gained from the isolation of a small peptide produced and from a study of the effect of several parameters on the rate of hydrolysis. Evidence obtained from electrophoresis and gel filtration allowed the assumption that attack on the sensitive bond resulted in a macropeptide and a small peptide of molecular weight about 2000. The small peptide was isolated and partially characterised. As a result it appears that the small peptide is derived from the C-terminal end of the β-casein molecule.

Introduction. Practical Examination 1 (Part A - Planning Exercise) Aim The aim of the experiment is to find out if the concentration of calcium ions has any effect on the rate of coagulation of milk. To do this I would vary the concentration of calcium ions and see how it affects coagulation. Prediction Rennin, also known as Chymosin, belongs to a family of enzymes called the aspartic proteinases (the reason that it belongs to this family is because it possesses an aspartic acid residue at the active site of the enzyme) and is a proteolytic enzyme synthesized by chief cells in the stomach. Its role in digestion is to curdle or coagulate milk in the stomach, a process of considerable importance in the very young animal. If milk were not coagulated, it would rapidly flow through the stomach and miss the opportunity for initial digestion of its proteins. Rennin efficiently converts liquid milk to a semisolid like cottage cheese, allowing it to be retained for longer periods in the stomach. ...read ...
Ancient people might have discovered rennet by storing fresh milk in a bag made from the stomach of a young animal, such as a lamb or calf, and discovering that the milk was changed into creamy lumps (called curds) and a liquid (called whey). Being adventurous souls, they tried the curds and whey and found that they were edible and perhaps even tasty. At any rate, the process preserved the milk so that it did not spoil so quickly. Humans soon realized that something in the lining of the fourth stomach of suckling animals caused this curdling effect and began to use this substance, called rennet.. ...
The rennet activity of chymo-trypsin (or pepsin) is conveniently measured by allowing a standard solution of milk to which chymotrypsin has been added to flow slowly through a graduated pipette and observing the rate and distance of flow of the milk before it clots. The time required for chymo-trypsin to clot milk may be calculated from these observations. The rennet activity is expressed as the reciprocal of the time in minutes required for 1 ml. of enzyme solution to clot 10 ml. of standard milk powder solution.. ...
We analysed the correlations of milk fermentability (yogurt test acidity), renneting (time to rennet coagulation of milk protein) and results of ethanol tests (indirect indicator of milk thermostability) with the percentages of the milk components. The correlations of the milk component percentages with renneting were mostly weak, while the correlations with the ethanol test were even poorer. The CSN3 and LGB genotypes did not show a significant interaction in their influence on milk fermentability, renneting or ethanol test results. For the ethanol test, many significant interactions were observed between the DGAT1, LEP, FASN, SCD1, CSN2, CSN3 and LGB genotypes. DGAT1 interacted significantly with all genes for milk fermentability. For renneting that was measured instrumentally, CSN3 interacted significantly with DGAT1, FASN, SCD1, CSN2 A/B, CSN2 A1/A2; SCD1 interacted significantly with LEP and FASN. The breed and genotypes did not show any interactions. Farm and genotypes interacted ...

Background and objectives Milk-clotting enzyme (MCE) has important applications in the dairy industry and in the cheese-manufacturing process. Because of the increase in cheese consumption and the low supply of calf rennets, there is a need for a suitable rennet substitute from an appropriate source. The present investigation aims at microbial production of MCE and medium optimization for maximal enzyme production by the most potent strain. Partial purification and the properties of the partially purified enzyme are also studied. Materials and methods In the present study several microorganisms were tested for production of the MCE. MCE/caseinase ratio was investigated and was used as the key parameter for selection of the most potent strain and for medium optimization. Medium optimization experiments were carried out in an attempt to increase the enzyme productivity by the most potent strain. The produced enzyme was partially purified using ammonium sulfate at 50% concentration and the ...

So his half-full glass of milk sat on the counter, where it fermented, festered and foamed, until vein-blue tentacles of mold grew over it. By some quirk of fate a little bit of rennet drooled into the mix. Rennet is a nice word for stomach mucus. It is beyond me to guess how stomach fluid got into his milk-one can only suppose the boy was under sixteen. The mother, to get rid of the growing stink, moved the festering blob of coagulating milk-fur into a nearby cave, where it continued cheerfully to rot ...

Introduction. Rennin in the Process of Cheese Making Aim Cheese manufacturers use rennin to speed up the time milk takes to clot so they can produce cheese quicker and thus being able to make more of it. The aim of this experiment is to find out the effect of temperature on the rate of milk clotting using rennin. Prediction I predict the colder the temperature of the reactants the slower the milk will clot and the warmer the reactants the faster the reaction will take place. I think this is because when cold, molecules move around slowly with there being much less successful collisions with other molecules because of the slower pace. But when warmer the molecules move around much faster because the have more kinetic energy from the heat, whizzing about all over the place and so there is going to be many more successful collisions than when the reactants were cold. But I also predict that when the enzyme has reached a certain high temperature, I think at about 55C the reactants will not clot ...

The structure of mucor pusillus pepsin (EC 3.4.23.6), the aspartic proteinase from Mucor pusillus, has been refined to a crystallographic R-factor of 16.2% at 2.0 A resolution. The positions of 2638 protein atoms, 221 solvent atoms and a sulphate ion have been determined with an estimated root-mean-square (r.m.s.) error of 0.15 to 0.20 A. In the final model, the r.m.s. deviation from ideality for bond distances is 0.022 A, and for angle distances it is 0.050 A. Comparison of the overall three-dimensional structure with other aspartic proteinases shows that mucor pusillus pepsin is as distant from the other fungal enzymes as it is from those of mammalian origin. Analysis of a rigid body shift of residues 190 to 302 shows that mucor pusillus pepsin displays one of the largest shifts relative to other aspartic proteinases (14.4 degrees relative to endothiapepsin) and that changes have occurred at the interface between the two rigid bodies to accommodate this large shift. A new sequence alignment ...
Action of clotting enzymes on camel milk.Most attempts to make cheese from camel milk have revealed major difficulties in getting the milk to coagulate. Initial field attempts increased the rennet concentration compared with that usually used for clotting cows milk by 50 to 100 times (Gast, Maubois and Adda, 1969; Wilson, 1984). More recent attempts confirm that the rennet coagulation of camel milk is two to four times slower than for cows milk treated under the same conditions (Ramet, 1985a; Farah and Bachmann, 1987; Ramet, 1987; Mohamed and Larsson-Raznikiewicz, 1990).. This specific behaviour has been observed with most of the clotting enzymes used for coagulation. Significant differences in the inhibition of clotting activity related to the origin of the enzyme have been noted, however. Several observations (Ramet, 1985a; Ramet, 1990) have shown that bovine pepsin coagulates camel milk well. Calf rennet and the clotting enzyme extracted from Mucor mieheihave an effect similar to but lower ...
Mozzarella, Swiss, Blue, Camembert). The milk for a second family of cheese varieties is coagulated by acidification. Acid-coagulated varieties, including Cottage cheese and Quark, differ from yogurt (which is essentially acid-gelled milk) by the fact that some moisture is removed in the form of whey whereas yogurt has nearly the same moisture content as milk.. Much cheese is now consumed in the form of processed cheese, e.g., on cheeseburgers. Processed cheese is produced by shredding and melting young natural cheese together with emulsifying salts into a smooth molten mass which is then cooled and moulded into the shape desired. Optional ingredients which may be added during the manufacture of processed cheese include milk powders, casein products, flavours, colours, preservatives and stabilizers. Much processed cheese is sold in the form of blocks or is moulded into large sheets which are then cut into ribbons, interleaved with film, stacked and cut to form convenient slices. Another ...
Diverse biological materials have been tested through the developed protocols, including insects of order Diptera (Drosophila), Hemiptera (family Cicadidae) cicada exuviae, yeast (Saccharomyces cerevisae), bacteria (Escherichia coli) and plants (Oryza sativa, Ipomoea batatas, Saintpaulia ionantha).. In the first protocol, which is chymosin-based, a work solution of calf rennet is prepared at 0.25 g/ml and maintained at -20ºC. We normally use the rennet Coalho em pó HA-LA (CHR HANSEN IND.COM.LTDA, Valinhos, SP, Brazil) purchased in supermarkets or in farm stores.. Roughly 100 mg of biological material, equivalent to a drop of blood, is homogenized in 600 µl of lysis buffer (0.1 M of Tris/HCl pH 8, 0.1 M of EDTA, 0.06 M of NaCl). Usually we perform this homogenization directly in a 1.5 ml microtube using a pistol homogenizer. After homogenization, 60 µl of 10% SDS is added and the tube is maintained in a water bath at 60ºC for one hour. After this, 60 µl of the rennet work solution is ...
Region-wise. North America and Europe are already at the saturation stage regarding cheese enzymes. However, the future belongs to the Asia-Pacific. The food habits of people are witnessing a paradigm shift. They are preferring cheese-oriented products for breakfast as well. This factor is bound to drive the cheese enzymes market in the near future.. How about Segmentation?. By source, cheese enzymes could be categorized into animal-based cheese enzymes, plant-based cheese enzymes, and micro-organism-based cheese enzymes. By type, it says lactase, fungus, lipase, catalyse, microbial rennet, chymosin, peptidases, proteases, and others. Citric acid and/or vinegar are used for congealing cheese. However, sour taste prevents its usage at a large scale. Rennet is the largest revenue generator. Though conventionally being an animal product, these days rennet is also made from microbes or plants. With predictability of reaction coupled with chemical purity, plant-based rennet is expected to gain ...
Learn about the different types of rennet, how to use them, and when to add rennet to milk when making cheese. Were here to help you make cheese from home.
Cheese is created when the casein (a protein) separates from the other parts of the milk. The two basic ways to make this happen are with rennet or with acid. The rennet or acid causes the casein and some other items to separate from the rest of the milk (a.k.a. the whey), and the newly formed item - known as curd - is further processed to become what we know as cheese. Although both methods remove casein from milk, they dont work in the same manner,1 and the curds produced by the two methods are quite different from one another. As a rule, milk curdled with rennet creates hard cheeses such as mozzarella, Muenster, pasteurized process (i.e. American cheese) and Swiss cheese, and acid-set cheeses are typically soft cheeses such as cottage cheese and cream cheese. Traditionally, rennet was derived from the calf stomachs, and Chazal forbade a non-Jews cheese as gevinas akum because of a concern that the cheese might be set with rennet from an animal that didnt have shechitah (i.e. a ...
Usually not, it will destroy whatever coagulation you have already gotten and the new rennet will not mix properly inside the curd that have already began to form. In some recipes of more acidic cheese you may be able to wait and see what happens. In harder cheeses its more sensitive and you would be better off trying to make cheese with the poor curd than waiting longer for it to harden (as it will give you acidic crumbly dry cheese that cant even melt ...

Direct surgical ligation or clipping is an increasing popular alternative to embolization. The traditional approach for ligation of the anterior and posterior ethmoids artery is via an external facial incision, but other approaches have been described, including an approach through the corner of the eye. Endoscopic sphenopalatine artery (SPA) ligation (Figure 3) throught the nose, has been proposed as an ideal treatment for certain nosebleeds as it takes the major arterial supply to the nasal cavity at a point closest to the bleeding, and therefore minimizes the risk of persistent bleeding from other circulation and spares the patient from a transoral incision. A review found a 92% to 100% success rate with endoscopic SPA ligation. Failures of this technique are attributed to the failure to identify all branches of the SPA, or the significant dissection that may be required in a patient with suboptimal coagulation properties ...
Their blood has altered coagulation properties, which increases their risk of both bleeding and thrombotic events such as stroke, as well as an increased risk of dying from other causes, the researchers said..

Some cheeses, particularly the harder ones like Parmesan, are almost always made with rennet. Others, like softer cheddars, do not use rennet and are therefore considered vegetarian. In the US, it can be hard to tell because the label often just says says enzymes, which may or may not be an animal product. There are non-animal derived coagulants and enzymes that are similar to rennet, but they are not perfect substitutes of each other.

Human-directed genetic manipulation of food began with the domestication of plants and animals through artificial selection at about 10,500 to 10,100 BC.[30]:1 The process of selective breeding, in which organisms with desired traits (and thus with the desired genes) are used to breed the next generation and organisms lacking the trait are not bred, is a precursor to the modern concept of genetic modification (GM).[30]:1[31]:1 With the discovery of DNA in the early 1900s and various advancements in genetic techniques through the 1970s[32] it became possible to directly alter the DNA and genes within food. The first genetically modified plant was produced in 1983, using an antibiotic-resistant tobacco plant.[33] Genetically modified microbial enzymes were the first application of genetically modified organisms in food production and were approved in 1988 by the US Food and Drug Administration.[34] In the early 1990s, recombinant chymosin was approved for use in several countries.[34][35] Cheese ...
As per Agnivesha in Charak Samhita one should never consume curd at night. Due to fermentation process curd by nature becomes very heavy to digest. It requires a good amount of metabolic activity in order to be digested thoroughly. Also, at the end of digestion curd increases Kapha and creates congestion in the channels which leads to poor lymphatic drainage. During the day when body is physically active it is easier to manage such congestion but at night when metabolic activity naturally slows down it may result in morning stiffness and water retention, thus leading to poor metabolic absorption (indigestion at cellular level). This is one another reason why curd has been contraindicated for people suffering with Rheumatoid arthritis or chronic indigestion. In order to maintain an optimum health one should never consume curd at night. Although, few other classical author believe that one can consume curd at night mixing it with other foods, but a critical analysis of the previous statement seems ...

I do want to tell you this...Parmigiano-Reggiano uses natural rennet, which allows for the long aging and is the traditional product. Grano Padano (which is not made at this factory) uses synthetic rennet and cannot be called Parmigiano-Reggiano. The classifications and distinctions are very important. What I learned at the factory, and what you would have seen in the video is, that buying the cheese with the rind still attached, meaning not already grated...is important. The classifications of the cheese are indicated on the rind. It receives a stamp if it is 1st quality. It also receives the stamp if it is second quality, but also has ridges cut into the rind. If it is 3rd quality, it does not receive a stamp and has all of the parmigiano reggiano marks ground out of it. This cheese is typically sold to companies that make american cheese. There is a price to pay for good ingredients and it is typically worth it. When it comes to cheese, it is definitely true ...

The NCLs present with progressive loss of visual function and neurodevelopmental decline, seizure, myoclonic jerks and premature death. The CTSD gene is one of the identified eight genes the deficiency of which is responsible for NCLs.[10] It has been reported that a homozygous single nucleotide duplication in exon 6 could alter the reading frame and causes a premature stop codon at position 255. Over-expression of cathepsin D stimulates tumorigenicity and metastasis as well as initiation of tumor apoptosis. This protease has been regarded an independent marker of poor prognosis in breast cancer being correlated with the incidence of clinical metastasis.[21][22] Knock-out of CTSD gene would cause intestinal necrosis and hemorrhage and increase apoptosis in thymus, indicating that cathepsin D is required in certain epithelial cells for tissue remodeling and renewal.[9] It is also reported that there might be a strong effect for CTSD genotype on Alzheimer disease risk in male.[23] Cathepsin D ...
Commercial pepsin is extracted from the glandular layer of hog stomachs. It is a component of rennet used to curdle milk during the manufacture of cheese. Pepsin is used for a variety of applications in food manufacturing: to modify and provide whipping qualities to soy protein and gelatin,[34] to modify vegetable proteins for use in nondairy snack items, to make precooked cereals into instant hot cereals,[35] and to prepare animal and vegetable protein hydrolysates for use in flavoring foods and beverages. It is used in the leather industry to remove hair and residual tissue from hides and in the recovery of silver from discarded photographic films by digesting the gelatin layer that holds the silver.[36] Pepsin was historically an additive of Beemans gum brand chewing gum by Dr. Edward E. Beeman. Pepsin is commonly used in the preparation of F(ab')2 fragments from antibodies. In some assays, it is preferable to use only the antigen-binding (Fab) portion of the antibody. For these applications, ...

The schists constitute a group of medium-grade metamorphic rocks, chiefly notable for the preponderance of lamellar minerals such as micas, chlorite, talc, hornblende, graphite, and others. Quartz often occurs in drawn-out grains to such an extent that a particular form called quartz schist is produced. By definition, schist contains more than 50% platy and elongated minerals, often finely interleaved with quartz and feldspar. Schist is often garnetiferous.. The individual mineral grains in schist, drawn out into flaky scales by heat and pressure, can be seen by the naked eye. Schist is characteristically foliated, meaning the individual mineral grains split off easily into flakes or slabs. The word schist is derived from the Greek word σχίζειν meaning "to split", which is a reference to the ease with which schists can be split along the plane in which the platy minerals lie.. Most schists have been derived from clays and muds which have passed through a series of metamorphic processes ...
The first part of the word is of obscure origin, but the first use of the term "coal" in English was as a reference to charcoal.[citation needed] In this compound term, the prefix "chare-" meant "turn", with the literal meaning being "to turn to coal". The independent use of "char", meaning to scorch, to reduce to carbon, is comparatively recent and is assumed to be a back-formation from the earlier charcoal. It may be a use of the word charren or churn, meaning to turn; i.e. wood changed or turned to coal, or it may be from the French charbon. A person who manufactured charcoal was formerly known as a collier (also as a wood collier). The word "collier" was also used for those who mined or dealt in coal, and for the ships that transported it.[citation needed]. ...

  • It contains an enzyme called Chymosin which makes the milk curdle/clot. (getrevising.co.uk)
  • The part of rennet that's most important for this process is called "chymosin," which is an enzyme called a protease, whose function is to break down other proteins. (scientificamerican.com)
  • The bacteria ( or yeast) on the left are modified by near-surgical precision to produce proteins - insulin and chymosin-while the one on the right is a plant whose "engineering" is akin to a blindfolded Goofy playing darts with transgenes. (gmonion.com)
  • In baby cows, chymosin is needed to break down the proteins in mother's milk, and that's why their stomachs are such an abundant source. (scientificamerican.com)
  • Enter genetically modified organisms: it's fairly trivial to make a bacterium or yeast cell that makes boatloads of chymosin - the exact same protein that's found in the stomachs of calves - without all of the fuss and bother attendant with raising and killing cows. (scientificamerican.com)
  • Trypsin and Chymotrypsin present in Chymosin are active enzymes (substances that speed up chemical reactions of the body). (24seven.com.np)
  • Biochemically, chymosin (IUB No. 3.4.4.3) is a protein consisting of a single polypeptide chain of 323 amino acids with intramolecular disulfide linkages. (inchem.org)
  • The protein chymosin, produced in the stomach, turned liquid milk into a semisolid form. (nytimes.com)
  • cDNA coding for bovine chymosin A was previously cloned and characterized. (inchem.org)
  • Preprochymosin is shortened by 16 amino acids during secretion and appears in the stomach as prochymosin, which, in turn, is activated to chymosin by cleavage of an additional 42 amino acids. (inchem.org)
  • This process is much more efficient because previously calves had to be slaughtered in order to extract the Chymosin from the inner lining of the stomach. (wikipedia.org)
  • The third type, chymosin rennet, is produced from genetically modified microorganisms. (ehow.com)
  • Despite having 85% sequence identity, camel chymosin shows a 70% higher milk-clotting activity than bovine chymosin towards bovine milk. (forskningsdatabasen.dk)
  • Glycosylation at Asn291 and the loss of the first three residues of camel chymosin significantly decreased its activity. (forskningsdatabasen.dk)
  • Thermal differential scanning calorimetry revealed a slightly higher thermal stability of camel chymosin compared with bovine chymosin. (forskningsdatabasen.dk)
  • The crystal structure of a doubly glycosylated variant of camel chymosin was determined at a resolution of 1.6 Å and the crystal structure of unglycosylated bovine chymosin was redetermined at a slightly higher resolution (1.8 Å) than previously determined structures. (forskningsdatabasen.dk)
  • Camel and bovine chymosin share the same overall fold, except for the antiparallel central β-sheet that connects the N-terminal and C-terminal domains. (forskningsdatabasen.dk)
  • In bovine chymosin the N-terminus forms one of the strands which is lacking in camel chymosin. (forskningsdatabasen.dk)
  • Variations in the amino acids delineating the substrate-binding cleft suggest a greater flexibility in the ability to accommodate the substrate in camel chymosin. (forskningsdatabasen.dk)
  • Camel chymosin contains two additional positive patches that favour interaction with the substrate. (forskningsdatabasen.dk)
  • The improved electrostatic interactions arising from variation in the surface charges and the greater malleability both in domain movements and substrate binding contribute to the better milk-clotting activity of camel chymosin towards bovine milk. (forskningsdatabasen.dk)
  • No. 9001-98-3), also known as chymosin (International Union of Biochemistry Enzyme Commission (E.C.) 3.4.23.4). (fda.gov)
  • 2) Chymosin preparation is a clear solution containing the active enzyme chymosin (E.C. 3.4.23.4). (fda.gov)
  • preprochymosin, prochymosin and chymosin. (nih.gov)
  • Chymosin is produced intracellularly as preprochymosin. (inchem.org)
  • In fact, chymosin produced by E. coli was the first of enzyme made with recombinant DNA technology approved for use in food. (scientificamerican.com)
  • And in any case, purified chymosin from E. coli is chemically indistinguishable from that taken from calves. (scientificamerican.com)
  • Commercial preparations of calf rennet contain two forms of chymosin, A and B, usually in the proportion of about 40% of A and 60% of B. Health aspects of rennet as a food ingredient were reviewed and evaluated at the fifteenth meeting of the Joint FAO/WHO Expert Committee on Food Additives in 1972 (Annex 1, reference 26). (inchem.org)
  • Most regulatory agencies don't consider chymosin an ingredient. (scientificamerican.com)
  • b) Rennet and chymosin preparation meet the general and additional requirements for enzyme preparations of the "Food Chemicals Codex," 3d Ed. (1981), pp. 107-110, which is incorporated by reference in accordance with 5 U.S.C. 552(a). (fda.gov)
