Hydrolysis of Peptides by Immobilized Bacterial Peptide Hydrolases

Applied Biochemistry and Microbiology, 2004
The feasibility of hydrolysis of a mixture of peptides with an enzyme from the bacterium Xanthomonas rubrilineans, displaying a peptidase activity and immobilized on aluminum oxide, was studied. Kinetic schemes and equations allowing one to approach quantitative descriptions of peptide hydrolysis in complex mixtures containing free amino acids and ...

Constructing peptide-based artificial hydrolases with customized selectivity

Journal of materials chemistry. B, 2019
The substrate selectivity of peptide-based artificial enzymes can be customized by combining molecularly imprinted polymers as binding sites with peptide nanofibers as catalytic moieties.

Characterization of an acid-stable peptide hydrolase and of peptide hydrolase a in germinated wheat

Phytochemistry, 1969
Abstract Peptide hydrolase A from germinated wheat has been separated from an acid-stable peptide hydrolase. The stability of these enzymes to pH and temperature and their K m values are described. Some peptides hydrolyzed by the acid-stable enzyme are reported.

Lysosomal hydrolases of the epidermis.

British Journal of Dermatology, 1975
Four distinct peptide hydrolases (EC 3-4) have been characterized in guinea-pig epidermis; these are cathepsin B1, cathepsin C, cathepsin D and arylamidase. Their properties are consistent with those of lysosomal enzymes. Cathepsin E was not detected.

Peptide hydrolase in wheat embryo

Phytochemistry, 1970
Abstract Commercial wheat embryo and embryo excised by hand from a hard red spring wheat (Selkirk) and a durum wheat (Leeds) were devoid of peptide hydrolase B. The embryo from all sources had an enzyme similar to peptide hydrolase A from germinated barley with respect to pH stability, thermal stability, and to the ratio of activity with α- N ...

A Study of Intraluminal Peptide Hydrolase Activity in the Rat

Clinical Science, 1975
1. Uncentrifuged and centrifuged rat intestinal contents were assayed for peptide hydrolase activity with glycyl-l-phenylalanine (Gly-Phe) and l-phenylalanyl-glycine (Phe-Gly) as substrates in the absence and presence of the intestinal cytosol peptide hydrolase inhibitor p-hydroxymercuribenzoate. 2.

Peptide hydrolase activities in rat muscle cultures

International Journal of Biochemistry, 1978
Abstract 1. 1. The specific activity of acid proteinase, cathepsin B1, arylamidase and cathepsin C was much higher in 2-day cultures of rat muscle than in mature muscle. Alkaline proteinase showed little or no difference. 2. 2. The total and specific activity of the enzymes, except alkaline proteinase, increased when the cultures were grown ...

A high-molecular weight peptide hydrolase in erythrocytes

International Journal of Biochemistry, 1982
1. A peptide hydrolase has been partially purified from the soluble fraction of erythrocyte lysates. 2. The enzyme has a molecular weight of approximately 600,000 and hydrolyses the chymotrypsin substrate glutaryl-Gly-Gly-Phe-7-amido-4-methylcoumarin (pH optimum 7.0) and the trypsin substrate CBZ-Gly-Gly-Arg-2-naphthylamide.

Peptide hydrolases in cotyledons of germinating lupin

Phytochemistry, 1993
Abstract Aminopeptidase (AP), carboxypeptidase (CP) and endopeptidase (EP) activities have been analysed in extracts prepared from cotyledons of dry and five and 14 days-germinated lupin seeds ( Lupinus albus ). At these three stages the pattern of the enzymatic activities change in a complex manner.

Peptide hydrolases in holothurian intestinal mucosa

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1981
Abstract 1. Peptide hydrolases from intestinal mucosa of H. forskali and N. mixta were studied by starch gel electrophoresis. 2. Dipeptides hydrolyzed were L -Leu- L -Leu and L -Gly- L -Leu. L-Gly- L -Tyr and L -Leu- L -Tyr were not 3. L -Leu- L -Leu- L -Leu-was hydrolyzed by extracts of both species. 4.
