[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 ...

Signal peptidases and signal peptide hydrolases

Journal of Bioenergetics and Biomembranes, 1990
Signal peptidases, the endoproteases that remove the amino-terminal signal sequence from many secretory proteins, have been isolated from various sources. Seven signal peptidases have been purified, two from E. coli, two from mammalian sources, and three from mitochondrial matrix.

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.

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.
