A high-molecular weight peptide hydrolase in erythrocytes
International Journal of Biochemistry, 19821. 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, 1993Abstract 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.

Developmental Changes in Peptide-Bond Hydrolases
1970The 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.

Artificial hydrolase based on carbon nanotubes conjugated with peptides
Nanoscale, 2016An 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 ...

[Brain peptide-hydrolase activity in hypothermia].
Ukrainskii biokhimicheskii zhurnal (1978), 1980The 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 ...

[Peptide hydrolases of marine organisms].
Ukrainskii biokhimicheskii zhurnal (1978), 1995The 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.

[Soluble neutral peptide hydrolases of nervous tissue].
Ukrains'kyi biokhimichnyi zhurnal, 1976Soluble forms of neutral peptide-hydrolases (protaminsulphate as a substrate) of the cat cerebral hemisphere grey and white matter were investigated by the method of gel-filtration on Sephadex G-150. The results of the experiments showed that grey and white matter of the cerebral hemispheres contains different forms of soluble neutral peptide ...
