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.

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 ...

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.

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 ...

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 ...

Rapid colorimetric assay for intestinal peptide hydrolases

Analytical Biochemistry, 1974
Abstract A simple two-step method is described for quantitating the release of free l -phenylalanine, l -leucine, l -methionine, or l -isoleucine from di- or polypeptides. The colorimetric assay is based on the ability of l -amino acid oxidase to catalyze the oxidation of free l -amino acid, but not of peptides.
