The effects of digestive enzymes on characteristics of placental insulin receptor. Comparison of particulate and soluble receptor preparations. (2/9857)

The role of the surrounding membrane structure on the binding characteristics of the insulin receptor was studied by using several digestive enzymes. The effects observed with particulate membrane preparations are compared with those from soluble receptor preparations. beta-Galactosidase and neuraminidase had no effect on insulin binding to either particulate or soluble receptors from human placentae. Exposure to 2 units of phospholipase C/ml increased insulin binding to particulate membranes, but was without effect on the soluble receptor preparation. The increase in binding to particulate membranes was shown to be due to an increase in apparent receptor number. After 5 min exposure to 500 microgram of trypsin/ml there was an increase in insulin binding to the particulate membrane fraction, owing to an increase in receptor affinity. After 15 min exposure to this amount of trypsin, binding decreased, owing to a progressive decrease in receptor availability. In contrast, this concentration of trypsin had no effect on the solubilized receptor preparation. Because of the differential effects of phospholipase C and trypsin on the particulate compared with the solubilized receptor preparations, it is concluded that the effects of these enzymes were due to an effect on the surrounding membrane structure. Changes in receptor configuration due to alterations within the adjoining membrane provide a potential mechanism for mediating short-term alterations in receptor function.  (+info)

Stable remodeling of tailless nucleosomes by the human SWI-SNF complex. (3/9857)

The histone N-terminal tails have been shown previously to be important for chromatin assembly, remodeling, and stability. We have tested the ability of human SWI-SNF (hSWI-SNF) to remodel nucleosomes whose tails have been cleaved through a limited trypsin digestion. We show that hSWI-SNF is able to remodel tailless mononucleosomes and nucleosomal arrays, although hSWI-SNF remodeling of tailless nucleosomes is less effective than remodeling of nucleosomes with tails. Analogous to previous observations with tailed nucleosomal templates, we show both (i) that hSWI-SNF-remodeled trypsinized mononucleosomes and arrays are stable for 30 min in the remodeled conformation after removal of ATP and (ii) that the remodeled tailless mononucleosome can be isolated on a nondenaturing acrylamide gel as a novel species. Thus, nucleosome remodeling by hSWI-SNF can occur via interactions with a tailless nucleosome core.  (+info)

The C-terminal region of hPrp8 interacts with the conserved GU dinucleotide at the 5' splice site. (4/9857)

A U5 snRNP protein, hPrp8, forms a UV-induced crosslink with the 5' splice site (5'SS) RNA within splicing complex B assembled in trans- as well as in cis-splicing reactions. Both yeast and human Prp8 interact with the 5'SS, branch site, polypyrimidine tract, and 3'SS during splicing. To begin to define functional domains in Prp8 we have mapped the site of the 5'SS crosslink within the hPrp8 protein. Immunoprecipitation analysis limited the site of crosslink to the C-terminal 5060-kDa segment of hPrp8. In addition, size comparison of the crosslink-containing peptides generated with different proteolytic reagents with the pattern of fragments predicted from the hPrp8 sequence allowed for mapping of the crosslink to a stretch of five amino acids in the C-terminal portion of hPrp8 (positions 1894-1898). The site of the 5'SS:hPrp8 crosslink falls within a segment spanning the previously defined polypyrimidine tract recognition domain in yPrp8, suggesting that an overlapping region of Prp8 may be involved both in the 5'SS and polypyrimidine tract recognition events. In the context of other known interactions of Prp8, these results suggest that this protein may participate in formation of the catalytic center of the spliceosome.  (+info)

Re-entering the translocon from the lumenal side of the endoplasmic reticulum. Studies on mutated carboxypeptidase yscY species. (5/9857)

Misfolded or unassembled secretory proteins are retained in the endoplasmic reticulum (ER) and subsequently degraded by the cytosolic ubiquitin-proteasome system. This requires their retrograde transport from the ER lumen into the cytosol, which is mediated by the Sec61 translocon. It had remained a mystery whether ER-localised soluble proteins are at all capable of re-entering the Sec61 channel de novo or whether a permanent contact of the imported protein with the translocon is a prerequisite for retrograde transport. In this study we analysed two new variants of the mutated yeast carboxypeptidase yscY, CPY*: a carboxy-terminal fusion protein of CPY* and pig liver esterase and a CPY* species carrying an additional glycosylation site at its carboxy-terminus. With these constructs it can be demonstrated that the newly synthesised CPY* chain is not retained in the translocation channel but reaches its ER lumenal side completely. Our data indicate that the Sec61 channel provides the essential pore for protein transport through the ER membrane in either direction; persistent contact with the translocon after import seems not to be required for retrograde transport.  (+info)

Reaction specificity of native and nicked 3,4-dihydroxyphenylalanine decarboxylase. (6/9857)

3,4-Dihydroxyphenylalanine (Dopa) decarboxylase is a stereospecific pyridoxal 5'-phosphate (PLP)-dependent alpha-decarboxylase that converts L-aromatic amino acids into their corresponding amines. We now report that reaction of the enzyme with D-5-hydroxytryptophan or D-Dopa results in a time-dependent inactivation and conversion of the PLP coenzyme to pyridoxamine 5'-phosphate and PLP-D-amino acid Pictet-Spengler adducts, which have been identified by high performance liquid chromatography. We also show that the reaction specificity of Dopa decarboxylase toward aromatic amines depends on the experimental conditions. Whereas oxidative deamination occurs under aerobic conditions (Bertoldi, M., Moore, P. S., Maras, B., Dominici, P., and Borri Voltattorni, C. (1996) J. Biol. Chem. 271, 23954-23959; Bertoldi, M., Dominici, P., Moore, P. S., Maras, B., and Borri Voltattorni, C. (1998) Biochemistry 37, 6552-6561), half-transamination and Pictet-Spengler reactions take place under anaerobic conditions. Moreover, we examined the reaction specificity of nicked Dopa decarboxylase, obtained by selective tryptic cleavage of the native enzyme between Lys334 and His335. Although this enzymatic species does not exhibit either decarboxylase or oxidative deamination activities, it retains a large percentage of the native transaminase activity toward D-aromatic amino acids and displays a slow transaminase activity toward aromatic amines. These transamination reactions occur concomitantly with the formation of cyclic coenzyme-substrate adducts. Together with additional data, we thus suggest that native Dopa decarboxylase can exist as an equilibrium among "open," "half-open," and "closed" forms.  (+info)

Enrichment of enzyme activity on deformylation of 1-NFK-lysozyme. (7/9857)

The formamide linkage of an inactive lysozyme derivative (1-NFK-lysozyme), formed by selective ozonization of tryptophan 62 in hen egg-white lysozyme [EC 3.2.1.17] was hydrolyzed with dilute acid faster in the frozen state at about --10 degrees than at 20 degrees. On hydrolysis of 1-NFK-lysozyme the low lytic activity increased to approximately 80% of that of native lysozyme. It is suggested that the binding ability associated with kynurenine 62 in the lysozyme derivative formed by this hydrolysis may be responsible for increase in enzymatic activity.  (+info)

Further studies on the mechanism of adrenaline-induced lipolysis in lipid micelles. (8/9857)

Lipase [EC 3.1.1.3] depleted lipid micelles, in which lipolysis was not elicited by adrenaline, were prepared from lipid micelles. When these lipase-depleted lipid micelles incubated with adipose tissue extract containing lipase activity, adrenaline-induced lipolysis was restored to almost the same level as that of native lipid micelles. Adrenaline-induced lipolysis was not restored when the lipase-depleted lipid micelles were homogenized or sonicated. Various tissue extracts from kidney, lung, liver, and pancreas, and post-heparin plasma, which contained lipase activity, restored adrenaline-induced lipolysis in lipase-depleted lipid micelles.  (+info)

1. A double-lumen perfusion technique has been used in man to study jejunal absorption of individual amino acids from an amino acid mixture simulating casein, and a tryptic hydrolysate of casein consisting of oligopeptides and amino acids.. 2. Total absorption was greater from the tryptic hydrolysate than from the amino acid mixture. There was wide variation in the extent to which individual amino acids were absorbed from the amino acid mixture. This was decreased when the tryptic hydrolysate was perfused. Amino acids which were particularly poorly absorbed from the amino acid mixture were absorbed to a substantially greater extent from the tryptic hydrolysate.. 3. The results suggest that the characteristics of absorption of amino acid mixtures do not represent those of absorption of the physiological products of intraluminal digestion, oligopeptides and amino acids.. ...
Trypsin (EC 3.4.21.4) is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyses proteins.[2][3] Trypsin is produced in the pancreas as the inactive proenzyme trypsinogen. Trypsin cleaves peptide chains mainly at the carboxyl side of the amino acids lysine or arginine, except when either is followed by proline. It is used for numerousbiotechnological processes. The process is commonly referred to as trypsin proteolysis or trypsinisation, and proteins that have been digested/treated with trypsin are said to have been trypsinized.. Activation of trypsin from proteolytic cleavage of trypsinogen in the pancreas can lead to a series of events that cause pancreatic self-digestion, resulting in pancreatitis. One consequence of the autosomal recessive disease cystic fibrosis is a deficiency in transport of trypsin and other digestive enzymes from the pancreas. This leads to the disorder termed meconium ileus. This disorder involves ...
SDS-PAGE was applied to determine trypsin activity and inhibition. After the hydrolysis by trypsin to substrate bovine serum albulnin (BSA) under different temperatures and pH, the hydrolysis degree of BSA was conducted using SDS-PAGE. From the quantitative analysis to the electrophoresis bands of BSA and its hydrolysis products in SDS-PAGE pattern, the change of trypsin activity was determined, and then the optimum temperature at 40°C and the optimum pH at pH 8.5 - 8.7 for trypsin activity were obtained. All the target bonds in BSA molecule could be hydrolyzed at the same time by trypsin. The inhibition was due to the binding of inhibitor to trypsin, which made it impossible for trypsin to touch the substrate protein. SDS-PAGE was demonstrated to be also an effect method for assaying the characteristics of trypsin activity and its inhibition.

Introduction. Investigation into the effects of trypsin on dried milk solution For this investigation we are only required to carry out the analysis and evaluation. We formulated our own hypotheses. The teacher carried out the experiment and provided us with the results. Aim: To investigate whether changing the concentration of trypsin affects the rate of which the proteins in milk are broken down. Hypothesis: My hypothesis is that the higher the concentration of enzyme the faster the proteins in the dried milk solution will be broken down. I expect my results graph to look like: I expect this because if the enzyme is more concentrated then there are more particles of the enzymes to collide with the substrate molecules and change them into products.

Chemically modified trypsin is a typical reagent in proteomics tests but is normally not considered in data source queries. database 127650-08-2 supplier search was used. Peptides were 127650-08-2 supplier matched using trypsin as a digestion enzyme. Peptides mass tolerance was set to 10 ppm (or 100 ppm for data set 5) and fragment mass tolerance to 0.8 Da. A maximum of two missed cleavages was allowed. Carbamidomethylation of cysteine was set as a fixed modification, and oxidation of methionine was set as a variable modification. To detect peptides made up of peptide c-terminal artificial amino acid J, we changed the cleavage specificity for trypsin to J, K, and R, not after P. Furthermore, to detect mixed (i.e., peptides including methylated and unmodified lysine) and monomethylated peptides, we added the loss of monomethylation (14.0153759 Da) and 127650-08-2 supplier loss of dimethylation (28.0307517 Da) of the artificial amino acid (J) as variable modifications. Data set 4 was searched ...
Trypsin is found in the digestive system, its a protease enzyme produced in the pancreas. Trypsin is an endopeptidase. This means that it cleaves amino acids in the middle of the polypeptide chain as opposed to cleaving the amino acids on the end of the polypeptide chain. It is a hydrolytic endopeptidase as it uses hydrolysis as the mechanism to break down polypeptides[1]. Trypsin is used in some proteomic investigations where the enzyme is used to cleave the peptide in question at specific points, at the C- terminal to Arginine and Lysine residues[2]. The resulting peptides can be recorded in a database, this data can be used to identify this protein in future studies[3]. ...

Introduction. Enzyme concentration and enzyme activity For this investigation, we are going to find out how different enzymes (in this case, trypsin) concentration in a solution would affect the rate of which solute (Casein) is broken down. I think enzyme concentration would definitely have an effect on the rate of reaction. My hypothesis is that increasing the concentration of trypsin would also increase the rate of catalysation of casein. Enzyme (a globular protein) is used to catalyse specific biological reactions by lowering the activation energy and they are left unchanged by the end of the reaction, for example trypsin is responsible for catalysing the break down of casein (a protein typically found in milk - it is what makes it ?opaque?) into smaller molecules which the body can absorb. This means the reaction can occur in a faster pace. This is important since without enzymes the molecule cannot break down fast enough on its own to provide us with constant nutrients. The reaction ...
Cultured cells must be passaged periodically to maintain their vigor and viability. Most commonly, researchers use trypsin, sometimes in combination with EDTA, to separate the adherent cells from their culture substrate and from each other. The amount of protease needed depends upon the cell type and the age of the culture. We offer trypsin from porcine pancreas in several strengths, and in a variety of media to optimize passaging conditions. Some formulations include the chelator EDTA. All have been sterile filtered and are thus ready-to-use. In addition, all solutions have been tested and are free of porcine parovirus.

In the original methods for 18O labeling, it was assumed that trypsin-catalyzed exchange reactions proceed completely to the doubly labeled (+4 Da) species (14, 15). Later it was acknowledged that although complete exchange is not always achieved, complete incorporation of at least one 18O atom was considered feasible in the practice. This allowed using quantification algorithms where the isotopic envelope of the peptide pairs was assumed to be composed by one isotopic cluster deriving from the non-labeled species, or sample A, and another two clusters deriving from the mono- (B1) and dilabeled (B2) species, which together compose the sample B (B = B1 + B2) (16-19). To achieve a complete incorporation of at least one oxygen, several labeling protocols have been described. A number of groups have reported efficient stable incorporation through a variety of ways, each one pointing out a set of recommendations to ensure the efficiency of the labeling process. The variability in the protocols spans ...
Insoluble fractions were resuspended in denaturing buffer consisting of 50% TFE in lysis buffer (50 mM Tris, 50 mM NaCl, 5 mM MgCl2). Soluble protein fractions were reduced to near-dry (,10 μl) by speedvac and resuspended in denaturing buffer (50% TFE in lysis buffer). All samples were then subjected to reduction, alkylation, and digestion with trypsin as previously described. Following digestion, trypsin activity was halted by the addition of 1% formic acid. Sample volume was reduced to [similar]100 μl by SpeedVac centrifugation and the volume adjusted to 150 μl with Buffer C (95% H2O, 5% acetonitrile (ACN), 0.1% formic acid). Tryptic peptides were bound and washed on Hypersep C-18 SpinTips (Thermo), eluted with 60% acetonitrile, 0.1% formic acid, reduced to near-dry by speedvac and resuspended in Buffer C.

A trypsin inhibitor (TI) is a protein and a type of serine protease inhibitor (serpin) that reduces the biological activity of trypsin by controlling the activation and catalytic reactions of proteins.[1] Trypsin is an enzyme involved in the breakdown of many different proteins, primarily as part of digestion in humans and other animals such as monogastrics and young ruminants. When trypsin inhibitor is consumed it acts as an irreversible and competitive substrate.[2] It competes with proteins to bind to trypsin and therefore renders it unavailable to bind with proteins for the digestion process.[1] As a result, protease inhibitors that interfere with digestion activity have an antinutritional effect. Therefore, trypsin inhibitor is considered an anti-nutritional factor or ANF.[3] Additionally, trypsin inhibitor partially interferes with chymotrypsin function. Trypsinogen is an inactive form of trypsin, its inactive form ensures protein aspects of the body, such as the pancreas and muscles, are ...
To study the inhibition mechanism of the native propeptide for the S. griseus trypsinogen, especially the role of the residue proline, we carried out molecular dynamics. Molecular dynamics (18) of the recombinants were simulated by the NAMD software with the CHARMM force field (http://www.ks.uiuc.edu/Research/namd) and comparatively analyzed with the active S. griseus trypsin (PDB ID, 1SGT). Total electrostatic energy in a particle mesh Ewald periodic box was calculated by the Ewald summation method, and the whole system was minimized using the descent method plus the conjugate gradient method. As shown in Fig. 4A, the major features of native trypsin were characterized. First, three disulfide bonds between residues C168 and C182, residues C191 and C220, and residues C42 and C58 held the substrate binding pocket rigid, and the correct fold was observed. Second, three hydrogen (H) bonds among the catalytic triad (H57, D102, and S195) maintained the accurate conformation of the catalytic center ...

Trypsin has been isolated and purified from the digestive glands of the slipper lobster, Thenus orientalis. It is a glycoprotein with a molecular mass of approximately 35 kDa as judged by both SDS-PAGE and gel filtration. The N-terminal amino acid sequence has strong homology to crustacean trypsins. This is confirmed by the cross-reaction of crustacean trypsins with antibodies to the T. orientalisenzyme. Despite a 40% identity with the bovine trypsin N-terminal sequence, there was no cross-reaction with the mammalian serine proteases. The optimum k(cat) and k(cat)/K(m) values for N-α-benzoylarginine-p-nitroanalide were 0.91 s⁻¹and 9.7 × 103M⁻¹s⁻¹, respectively, with this specificity constant being lower than those reported for other crustacean trypsins. Inhibition studies indicated the presence of serine and histidine at the active site and pKₐ of the catalytic histidine residue was found to be 5.7 in the free enzyme and 4.7 in the Michaelis complex.. ...
Recombinant Trypsin EDTA Solution is a defined, animal component-free solution developed for efficient dissociation of adherent cell types from culture surfaces and tissues. The EDTA component accelerates the dissociative action of the enzyme trypsin. This solution is suitble for sensitive cells types, including human mesenchymal stem cells (hMSC).. The Recombinant Trypsin EDTA Solution is a pure enzyme solution, which maximises the yield of functionally viable cells from culture dishes. The lack of other proteases reduces the risk of toxicity being induced in the cells. This solution does not contain undesirable proteins such as carboxypeptidase A and chymotrypsin, which are commonly found in other commercially available trypsin solutions. Recombinant Trypsin EDTA Solution is animal component-free, so eliminates the risk of viruses and other potentially detrimental and unintended agents associated with animal-derived components.. ...

Again, the results are going to depend on the sample prep method you use. In my case - I work with complex samples, e.g. cell pellets or tissues, and extract all proteins with SDS right away. When the low % of the missed cleavages is required, I prefer using Lys-C and trypsin simultaneously and the only commercially available enzyme mix at this moment is from Promega. I use basic trapping digest with S-Trap (STrap) method which is, in my opinion, ideal for processing of complex samples. Now, the numbers: for the fast 2-hour digest I get about 30% (trypsin only) and 15% (enzyme mix) of the missed cleavages, for the overnight digest I get about 17% (trypsin only) and 8.5% (enzyme mix) of the missed cleavages. The lower % of the missed cleavages does not necessarily mean the perceptible increase in the number of protein ids, though ...
A method for peptide mapping of tryptic digests on cellulose this layers was developed. The method was much more sensitive than procedures based on paper or column separation techniques, and enabled the detection of many peptides resulting from non-specific tryptic hydrolysis during protein digestion. An E-coli cell-free protein synthesizing system directed by R17 RNA was used to examine the fidelity of translation in vitro. The major product of this system, the coat protein, was separated from the in vitro reaction mixtures and analysed by the peptide mapping procedure. A series of experiments utilising radioactive amino acids established that the fidelity of translation was high, and enabled the identification of the mapping position of the major tryptic peptides ...

Our study is the first to examine systematically the structure-activity relationships for the activation of PAR2 by its tethered ligand sequence. The main finding of our study was that the first two amino acids of the tethered ligand of rat PAR2, in tandem, play a key role in receptor activation. This conclusion was supported by the data indicating that the revealed tethered ligand SLAAAA... was able to generate a substantial calcium signal in response to trypsin, whereas the receptor mutants with revealed tethered ligands AAIGRL..., ALAAAA..., and LSIGRL... generated little or no calcium signal in response to trypsin. Thus, the SL... motif on its own as a tethered ligand was sufficient to generate a substantial receptor signal. This activity for the tethered ligand would not have been predicted because the soluble PAR2AP SLAAAA-NH2 did not activate PAR2wt.. To interpret the sensitivity to trypsin (calcium signal) as reflecting the activity of the tethered ligand, it was important to establish ...
