Developmental Changes in Peptide-Bond Hydrolases [PDF]

open access: yes, 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.

Intestinal surface peptide hydrolases: Identification and characterization of three enzymes from rat brush border [PDF]

open access: yesBiochimica Et Biophysica Acta - Biomembranes, 1975
Peptide hydrolases were solubilized from rat small intestinal brush border by papain and separated by Sephadex G-200 chromatography, velocity gradient ultracentrifugation and polyacrylamide disc electrophoresis and designated according to approximate ...

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 ...

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.

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 ...
