The amino acid sequence of Neurospora NADP-specific glutamate dehydrogenase. Peptic and chymotryptic peptides and the complete sequence. (1/1155)Peptic and chymotryptic peptides were isolated form the NADP-specific glutamate dehydrogenase of Neurospora crassa and substantially sequenced. Out of 452 residues in the polypeptide chain, 265 were recovered in the peptic and 427 in the chymotryptic peptides. Together with the tryptic peptides [Wootton, J. C., Taylor, J. G., Jackson, A. A., Chambers, G. K. & Fincham, J. R. S. (1975) Biochem. J. 149, 749-755], these establish the complete sequence of the chain, including the acid and amide assignments, except for seven places where overlaps are inadequate. These remaining alignments are deduced from information on the CNBr fragments obtained in another laboratory [Blumenthal, K. M., Moon, K. & Smith, E. L. (1975), J. Biol. Chem. 250, 3644-3654]. Further information has been deposited as Supplementary Publication SUP 50054 (17 pages) with the British Library (Lending Division), Boston Spa, Wetherby, W. Yorkshire LS23 7BQ, U.K., from whom copies may be obtained under the terms given in Biochem. J. (1975) 145, 5. (+info)
The role of the flap residue, threonine 77, in the activation and catalytic activity of pepsin A. (2/1155)Flexible loops, often referred to as flaps, have been shown to play a role in catalytic mechanisms of different enzymes. Flaps at the active site regions have been observed in the crystal structures of aspartic proteinases and their residues implicated in the catalytic processes. This research investigated the role of the flap residue, threonine 77, in the activation of pepsinogen and the catalytic mechanism of pepsin. Three mutants, T77S, T77V and T77G, were constructed. Differences in amino acid polarity and hydrogen bonding potential were shown to have an influence on the activation and catalytic processes. T77S activated at the same rate and had similar catalytic parameters as the wild-type pepsin. The activation rates of T77V and T77G were slower and their catalytic efficiencies lower than the wild-type. The results demonstrated that the threonine 77 polar side chain played a role in a proteolysis. The contribution of the side chain to zymogen activation was associated with the proteolytic cleavage of the prosegment. It was postulated that the hydroxyl group at position 77 provided an essential hydrogen bond that contributed to proper substrate alignment and, indirectly, to a catalytically favorable geometry of the transition state.

Isolation and identification of three bactericidal domains in the bovine alpha-lactalbumin molecule. (3/1155)Proteolytic digestion of alpha-lactalbumin by pepsin, trypsin and chymotrypsin yielded three polypeptide fragments with bactericidal properties. Two fragments were obtained from the tryptic digestion. One was a pentapeptide with the sequence EQLTK (residues 1-5) and the other, GYGGVSLPEWVCTTF ALCSEK (residues (17-31)S-S(109-114)), was composed of two polypeptide chains held together by a disulfide bridge. Fragmentation of alpha-lactalbumin by chymotrypsin yielded CKDDQNPH ISCDKF (residues (61-68)S-S(75-80)), also a polypeptide composed of two polypeptide chains held together by a disulfide bridge. The three polypeptides were synthesized and found to exert antimicrobial activities. The polypeptides were mostly active against Gram-positive bacteria. Gram-negative bacteria were only poorly susceptible to the bactericidal action of the polypeptides. GYGGVSLPEWVCTTF ALCSEK was most, EQLTK least bactericidal. Replacement of leucine (23) with isoleucine, having a similar chemical structure but higher hydrophobicity, in the sequence GYGGVSLPEWVCTTF ALCSEK significantly reduced the bactericidal capacity of the polypeptide. Digestion of alpha-lactalbumin by pepsin yielded several polypeptide fragments without antibacterial activity. alpha-Lactalbumin in contrast to its polypeptide fragments was not bactericidal against all the bacterial strains tested. Our results suggest a possible antimicrobial function of alpha-lactalbumin after its partial digestion by endopeptidases. (+info)
Recombinant human type II collagens with low and high levels of hydroxylysine and its glycosylated forms show marked differences in fibrillogenesis in vitro. (4/1155)Type II collagen is the main structural component of hyaline cartilages where it forms networks of thin fibrils that differ in morphology from the much thicker fibrils of type I collagen. We studied here in vitro the formation of fibrils of pepsin-treated recombinant human type II collagen produced in insect cells. Two kinds of type II collagen preparation were used: low hydroxylysine collagen having 2.0 hydroxylysine residues/1,000 amino acids, including 1.3 glycosylated hydroxylysines; and high hydroxylysine collagen having 19 hydroxylysines/1,000 amino acids, including 8.9 glycosylated hydroxylysines. A marked difference in fibril formation was found between these two kinds of collagen preparation, in that the maximal turbidity of the former was reached within 5 min under the standard assay conditions, whereas the absorbance of the latter increased until about 600 min. The critical concentration with the latter was about 10-fold, and the absorbance/microgram collagen incorporated into the fibrils was about one-sixth. The morphology of the fibrils was also different, in that the high hydroxylysine collagen formed thin fibrils with essentially no interfibril interaction or aggregation, whereas the low hydroxylysine collagen formed thick fibrils on a background of thin ones. The data thus indicate that regulation of the extents of lysine hydroxylation and hydroxylysine glycosylation may play a major role in the regulation of collagen fibril formation and the morphology of the fibrils.

Monkey pepsinogens and pepsins. III. Carbohydrate moiety of Japanese monkey pepsinogens and the amino acid sequence around the site of its attachment to protein. (5/1155)Purified Japanese monkey pepsinogens I and II contain carbohydrate as a part of the enzyme molecule. By gel filtration on Sephadex G-100, chromatography on DE-32 cellulose, and polyacrylamide disc gel electrophoresis, the carbohydrate moiety could not be separated from the enzyme protein, and the content did not decrease on repeated chromatography. Glycopeptides were obtained by successive digestion of pepsinogens with thermolysin and aminopeptidases and isolated by chromatography on Sephadex G-25 and G-50. Identification and determination of carbohydrate components was performed by paper and gas-liquid chromatographies. The presence of 4 glucosamines, 6 galactoses, 6--8 mannoses, and 8--11 fucoses per molecule of the glycopeptide of both pepsinogens was observed, of which the high content of fucose is especially unique. The molecular weight of the carbohydrate chains should be around 4,000--5,000. The amino acid sequence of a major glycopeptide was deduced to be Ile-Gly-Ile-Gly-Thr-Pro-Gln-Ala-Asn, in which the asparagine residue is the site of attachment of the carbohydrate chain. (+info)
Larynx vs. esophagus as reflexogenic sites for acid-induced bronchoconstriction in dogs. (6/1155)Bronchoconstriction in asthmatic patients is frequently associated with gastroesophageal reflux. However, it is still unclear whether bronchoconstriction originates from the esophagus or from aspiration of the refluxate into the larynx and larger airway. We compared the effect of repeated esophageal and laryngeal instillations of HCl-pepsin (pH 1.0) on tracheal smooth muscle activity in eight anesthetized and artificially ventilated dogs. Saline was used as control. We used pressure in the cuff of an endotracheal tube (Pcuff) as a direct index of smooth muscle activity at the level of the larger airways controlled by vagal efferents. The Pcuff values of the first 60 s after instillations were averaged, and the difference from the baseline values was evaluated. Changes in Pcuff were significantly greater with laryngeal than with esophageal instillations (P = 0.0166). HCl-pepsin instillation into the larynx evoked greater responses than did saline (P = 0.00543), whereas no differences were detected with esophageal instillations. Repeated laryngeal exposure enhanced the responsiveness significantly (P < 0. 001). Our data indicate that the larynx is more important than the esophagus as a reflexogenic site for the elicitation of reflex bronchoconstriction in response to acidic solutions. (+info)
Vagal esophageal receptors in anesthetized dogs: mechanical and chemical responsiveness. (7/1155)This study was performed to evaluate the characteristics of esophageal receptors in anesthetized and artificially ventilated dogs. The electrical activity of the esophageal afferents was recorded from the peripheral cut end of the cervical vagus nerve. A cuffed catheter was inserted into the esophagus at the level of the third tracheal ring and was used to establish the esophageal location of the endings. Most of the receptors were localized in the intrathoracic portion of the esophagus. The majority of the receptors studied (36 of 43) showed a slow adaptation to a maintained stretch of the esophageal wall. Vagal cooling blocked receptor activity at temperatures ranging from 3.5 to 25 degrees C. Twenty-eight of 43 receptors, including 4 rapidly adapting endings (RAR), were challenged with saline, HCl + pepsin (HCl-P; pH 1) and distilled water (8 ml, 37 degrees C). HCl-P solutions specifically stimulated only three receptors; saline or water did not. Five slowly adapting receptors and two RARs were also challenged with topically applied capsaicin; only one RAR was stimulated. To ascertain a possible effect of smooth muscle contraction, 17 receptors were tested with intravenous injections of ACh and/or asphyxia; only 4 were stimulated. These characteristics do not support an important reflexogenic role of the esophagus in response to chemical stimuli. (+info)
Contribution of a prosegment lysine residue to the function and structure of porcine pepsinogen A and its active form pepsin A. (8/1155)A conserved lysine residue, Lys36p, on the prosegment of pepsinogen was replaced with a positively charged arginine (K36pR), a negatively charged glutamic acid (K36pE), and a neutral side chain methionine (K36pM). K36pM and K36pE mutants were extremely unstable and degraded rapidly, especially K36pE, which was inactivated during purification. This instability was confirmed by microcalorimetry where the denaturing temperatures for K36pM and K36pE were 6 degrees C and 10 degrees C lower than the wild-type, respectively. As a function of pH, K36pM and K36pR were activated over a broader range of pH as compared with wild-type. The mutant pepsinogens were activated faster than wild-type with K36pM being activated approximately 10 times faster. The activated pepsins from the various mutant pepsinogens showed lower kinetic efficiency than wild-type enzyme. Catalytic rate constants were reduced by half. The results suggested Lys36p is important for the correct folding of the active-centre residues. The molecular modeling calculation suggested that the position of Asp215 was substantially altered. In conclusion, the above results would suggest that Lys36p was important not only for stability of the prosegment and pepsinogen, but also for the correct alignment of the active-centre residues.

Pepsin A is a digestive enzyme that is produced in the lining of the stomach. It is responsible for breaking down proteins into smaller peptides and amino acids, which can then be absorbed by the body. Pepsin A is activated by hydrochloric acid, which is also produced in the stomach, and is typically secreted in an inactive form called pepsinogen. Once it is activated, pepsin A has a pH optimum of around 2, which is the acidic environment of the stomach. It is an important part of the digestive process and is involved in the breakdown of many different types of proteins, including those found in meat, dairy products, and eggs.
Pepsinogens are inactive precursors of the digestive enzyme pepsin, which is produced in the stomach lining. There are two main types of pepsinogens: pepsinogen A and pepsinogen B. Pepsinogen A is produced by chief cells in the stomach lining and is found in the stomach juice. Pepsinogen B is produced by parietal cells in the stomach lining and is also found in the stomach juice. Pepsinogens are activated to pepsin by hydrochloric acid, which is produced by parietal cells in the stomach lining. Pepsin then breaks down proteins in the food we eat, helping to digest them. In the medical field, pepsinogens are often measured in blood or stool samples as a way to diagnose and monitor certain conditions, such as stomach ulcers, gastritis, and Helicobacter pylori infection. High levels of pepsinogens in the blood or stool may indicate inflammation or damage to the stomach lining, while low levels may indicate a deficiency in stomach acid production.
Pepstatins are a class of synthetic peptides that are used as inhibitors of aspartic proteases, a type of protease enzyme that cleaves proteins at aspartic acid residues. These proteases are involved in a variety of biological processes, including digestion, blood clotting, and the immune response. Pepstatins are often used in research to study the function of aspartic proteases and to develop new drugs for the treatment of diseases that are caused by the overactivity of these enzymes. They are also used as diagnostic tools to detect the presence of certain diseases, such as cancer and viral infections.
Respiratory aspiration is a medical condition that occurs when a person inhales foreign material into their lungs. This can happen when a person is unconscious, has difficulty swallowing, or has a weakened cough reflex, among other reasons. Aspiration can lead to a variety of complications, including pneumonia, lung abscesses, and respiratory failure. Treatment for respiratory aspiration typically involves removing the foreign material from the lungs and providing supportive care to manage any complications that may arise.
Pentagastrin is a synthetic peptide that stimulates the release of gastric acid and other digestive enzymes from the stomach. It is commonly used in medical research and diagnostic testing to evaluate the function of the stomach and its digestive system. Pentagastrin is typically administered intravenously or orally, and its effects can be measured through various methods, such as pH monitoring or enzyme assays. In some cases, pentagastrin may also be used to treat certain digestive disorders, although its use in this context is limited and typically reserved for cases where other treatments have been ineffective.
Pepsinogen A is a precursor protein of the digestive enzyme pepsin, which is produced in the chief cells of the stomach lining. Pepsinogen A is inactive until it is converted to pepsin by hydrochloric acid in the stomach. Pepsin then helps to break down proteins in the food we eat, making them easier to digest and absorb. Pepsinogen A levels can be measured in blood or stool samples as a diagnostic tool for certain medical conditions, such as stomach cancer or Zollinger-Ellison syndrome, which is a condition characterized by excessive stomach acid production.
Pancreatin is a mixture of digestive enzymes that are produced by the pancreas. It is typically used as a medication to help with the digestion of food in people who have digestive disorders or who are unable to produce enough digestive enzymes on their own. Pancreatin contains enzymes such as amylase, lipase, and protease, which help to break down carbohydrates, fats, and proteins in food, respectively. It is available in various forms, including tablets, capsules, and liquid, and is usually taken with meals.
Norleucine is an amino acid that is similar in structure to leucine, but with one carbon atom removed. It is a non-essential amino acid, meaning that it can be synthesized by the body and is not required to be obtained through the diet. Norleucine is found in small amounts in many foods, including meat, dairy products, and eggs. In the medical field, norleucine is sometimes used as a nutritional supplement or as a component of certain medications. It has been studied for its potential effects on muscle growth and development, as well as its potential role in treating certain medical conditions, such as liver disease and cancer.
Chymosin is an enzyme that is produced by the cells of the fourth stomach of ruminant animals, such as cows and sheep. It is also known as rennin, and is used in the production of cheese. In the medical field, chymosin is used to help digest proteins in the stomach and small intestine. It is also used to treat certain digestive disorders, such as lactose intolerance and acid reflux. Chymosin is available as a medication and is usually taken by mouth.
Aspartic acid endopeptidases are a class of enzymes that cleave peptide bonds in proteins, specifically at the carboxyl side of aspartic acid residues. These enzymes are involved in various physiological processes, including digestion, blood clotting, and the regulation of hormone levels. In the medical field, aspartic acid endopeptidases are often studied for their potential therapeutic applications, such as in the treatment of cancer, neurodegenerative diseases, and infections. They are also used as research tools to study protein structure and function, and to develop new drugs and diagnostic tests.
Pneumonia, aspiration is a type of pneumonia that occurs when bacteria, viruses, or other foreign substances are inhaled into the lungs and cause an infection. Aspiration pneumonia occurs when a person inhales food, liquid, or other substances into their lungs, which can lead to the growth of bacteria or other microorganisms in the lungs. This can cause inflammation and damage to the lung tissue, leading to symptoms such as coughing, fever, chest pain, and difficulty breathing. Aspiration pneumonia is more common in people who have difficulty swallowing or who have conditions that affect their ability to protect their airway, such as stroke or dementia. Treatment for aspiration pneumonia typically involves antibiotics to treat the infection and supportive care to help the person breathe more easily.
Hair diseases, also known as hair disorders, are medical conditions that affect the growth, structure, or appearance of hair. These conditions can be inherited or acquired and can affect any part of the body where hair grows, including the scalp, face, eyebrows, eyelashes, and pubic hair. Some common hair diseases include alopecia areata, which causes patches of hair loss, and androgenetic alopecia, which is a genetic condition that causes hair loss on the scalp. Other hair diseases include trichotillomania, which is the compulsive pulling of hair, and tinea capitis, which is a fungal infection of the scalp that can cause hair loss. Hair diseases can be treated with medications, hair transplantation, or other medical procedures. In some cases, lifestyle changes or dietary modifications may also be recommended to help manage the condition. It is important to consult a healthcare professional if you are experiencing hair loss or other symptoms of a hair disease.
Osteochondrodysplasias are a group of genetic disorders that affect the development of bones and cartilage. These disorders are characterized by abnormal growth and development of the skeletal system, leading to various skeletal abnormalities such as short stature, deformities of the limbs, and joint problems. Osteochondrodysplasias can be inherited in an autosomal dominant or recessive manner, and they can affect both children and adults. Some of the most common types of osteochondrodysplasias include achondroplasia, thanatophoric dysplasia, hypochondroplasia, and multiple epiphyseal dysplasia. Diagnosis of osteochondrodysplasias typically involves a combination of physical examination, medical history, and imaging studies such as X-rays and MRI. Treatment options may include physical therapy, surgery, and medications to manage symptoms and improve quality of life.
Severe Combined Immunodeficiency (SCID) is a rare genetic disorder that affects the immune system. It is characterized by a severe and combined deficiency of both T cells and B cells, which are essential components of the immune system that help the body fight off infections and diseases. SCID can be caused by mutations in one of several genes that are involved in the development and function of the immune system. These mutations can result in the inability of the body to produce functional T cells and B cells, leaving the individual vulnerable to infections that would normally be easily fought off by a healthy immune system. Symptoms of SCID can include recurrent and severe infections, failure to thrive, and delayed development. Without treatment, SCID can be life-threatening, but it can be managed with bone marrow transplantation or gene therapy.
Cartilage diseases refer to a group of medical conditions that affect the cartilage tissue in the body. Cartilage is a flexible, rubbery connective tissue that covers the ends of bones, provides cushioning between joints, and helps to maintain the shape of certain structures in the body. There are several types of cartilage diseases, including: 1. Osteoarthritis: This is the most common type of cartilage disease, which occurs when the cartilage that cushions the joints breaks down, leading to pain, stiffness, and reduced mobility. 2. Rheumatoid arthritis: This is an autoimmune disorder that causes inflammation and damage to the cartilage and other tissues in the joints. 3. Osteochondritis dissecans: This is a condition in which a piece of cartilage and underlying bone separates from the joint surface, causing pain and swelling. 4. Chondromalacia patellae: This is a condition that affects the cartilage under the kneecap, causing pain and swelling. 5. Ectopic ossification: This is a condition in which bone forms in soft tissues, such as the muscles or tendons, leading to pain and limited mobility. 6. Chondrosarcoma: This is a rare type of cancer that develops in the cartilage tissue, causing pain, swelling, and other symptoms. Treatment for cartilage diseases depends on the specific condition and severity of the symptoms. It may include medications, physical therapy, lifestyle changes, and in some cases, surgery.
In the medical field, a syndrome is a set of symptoms and signs that occur together and suggest the presence of a particular disease or condition. A syndrome is often defined by a specific pattern of symptoms that are not caused by a single underlying disease, but rather by a combination of factors, such as genetic, environmental, or hormonal. For example, Down syndrome is a genetic disorder that is characterized by a specific set of physical and intellectual characteristics, such as a flattened facial profile, short stature, and intellectual disability. Similarly, the flu syndrome is a set of symptoms that occur together, such as fever, cough, sore throat, and body aches, that suggest the presence of an influenza virus infection. Diagnosing a syndrome involves identifying the specific set of symptoms and signs that are present, as well as ruling out other possible causes of those symptoms. Once a syndrome is diagnosed, it can help guide treatment and management of the underlying condition.
VDJ recombination, also known as V(D)J recombination, is a process that occurs in the immune system to generate a diverse repertoire of antibodies and T cell receptors. This process involves the rearrangement of gene segments encoding the variable regions of these receptors, which are then assembled into functional receptors that can recognize specific antigens. VDJ recombination occurs in two stages: V(D)J recombination-activating gene (RAG) mediated cleavage and nonhomologous end joining (NHEJ) or homologous recombination (HR) repair. During the first stage, the RAG proteins cleave the DNA at specific sites to generate double-strand breaks. These breaks are then repaired by NHEJ or HR, which can result in the deletion, insertion, or translocation of DNA segments. The VDJ recombination process is essential for the development of a diverse and functional immune system, as it allows for the generation of a vast array of unique receptors that can recognize a wide range of antigens. Mutations in the genes encoding the RAG proteins or the factors involved in NHEJ or HR can lead to immunodeficiency or autoimmune disorders.
