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.

[Hydrolysis of peptides by immobilized bacterial peptide hydrolases].

Prikladnaia biokhimiia i mikrobiologiia, 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 for approaching quantitative description of peptide hydrolysis in complex mixtures containing free amino acids and ...

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 ...

Peptide‐Based Catalyst Mimicking Hydrolase Enzyme

Journal of Peptide Science
ABSTRACTPeptide‐based nanomolecular constructs offer great possibilities for designing catalytic molecular systems mimicking enzymes. In this study, we designed three tripeptide catalysts that can possibly mimic hydrolase enzymes, with the objective of systematically verifying the scope of modulating enzymatic activity.

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 ...

Photothermally switchable peptide nanostructures towards modulating catalytic hydrolase activity

Nanoscale, 2021
The Aβ42 amyloid-inspired peptide fragment renders pathway-driven self-assembled nanostructures mediated by heat, light and chemical cues. They are envisaged as robust biocatalysts with remarkable variation of the hydrolase catalytic efficiency.

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.

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.

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.
