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.

Enzyme‐mediated peptide synthesis using acylpeptide hydrolase

European Journal of Biochemistry, 1991
Acylpeptide hydrolase is shown to catalyse the specific addition of a single amino acid to the N‐terminus of a peptide. The stabilised Sepharose‐coupled form of the enzyme is used to couple a carboxy‐methylated N‐formyl (or N‐acetyl) amino acid to a short pre‐existing peptide.

Artificial hydrolase based on carbon nanotubes conjugated with peptides

Nanoscale, 2016
An artificial enzyme was constructed by attaching short peptides with active sites (SHELKLKLKL, WLKLKLKL) onto carbon nanotubes (CNT). It was found that the combination of SHE amino acids was essential to form a catalytic triad. W was also incorporated into this artificial enzyme and acted as a substrate binding site, thus producing an enzyme model ...

Developmental Changes in Peptide-Bond Hydrolases

1970
The rapid growth of brain during ontogeny affords a valuable experimental tool for studying the factors affecting protein breakdown and turnover. Despite the wealth of information documenting the remarkable changes during developmental(1–5) the correlation between chemical events and functional changes is poorly understood.

[Peptide hydrolases of marine organisms].

Ukrainskii biokhimicheskii zhurnal (1978), 1995
The survey is devoted to the description of properties of proteolytic enzymes of some sea organisms. Structure peculiarities and properties of proteinases of trypsin and chymotrypsin type, carboxypeptidases A and B, aminopeptidase and leucine aminopeptidase of molluscs, stars, shrimps, fishes and other sea organisms have been considered.

[Brain peptide-hydrolase activity in hypothermia].

Ukrainskii biokhimicheskii zhurnal (1978), 1980
The cooling of rats to the body temperature of 30 and 25 degrees C does not change acidic peptide-hydrolase activity in tissue homogenates of cerebral cortex, hypothalamus, thalamus, hippocampus, midbrain, cerebellum and medulla oblongata. In deep hypothermia (to 20 degrees C) there occurs a significant increase in the peptide-hydrolase activity in ...
