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 ...

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.

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 hydrolases in cotyledons of germinating lupin

Phytochemistry, 1993
Abstract 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.

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.

Peptide hydrolases in spinal cord and brain of the rabbit

Brain Research, 1972
Summary Spinal cord and brain fractions from rabbits were compared in terms of their content of free amino acids, the amino acid composition of their proteins, and the level of selected proteases and peptidases. The amino acid composition of poteins in the cervical, thoracic and lumbar areas of the cord were similar, and no major differences were ...

A Study of Intraluminal Peptide Hydrolase Activity in the Rat

Clinical Science, 1975
1. Uncentrifuged and centrifuged rat intestinal contents were assayed for peptide hydrolase activity with glycyl-l-phenylalanine (Gly-Phe) and l-phenylalanyl-glycine (Phe-Gly) as substrates in the absence and presence of the intestinal cytosol peptide hydrolase inhibitor p-hydroxymercuribenzoate. 2.

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 ...

PROTEIN AND PEPTIDE HYDROLASES OF THE RAT HYPOTHALAMUS AND PITUITARY

Journal of Neurochemistry, 1974
AbstractPeptide and peptidyl‐peptide hydrolase activities were measured in the cerebral cortex, adenoand neurohypophysis, anterior and posterior regions of the hypothalamus to assess regional differences in peptide hormone turnover. In general all enzyme activities were higher in the pituitary except for the monoacyl arylamidase which was lower, and ...
