The specific esterase activity of trypsin.
The discovery of relatively simple peptide derivatives as substrates for proteolytic enzymes has introduced a new approach to the problem of the specificity of this group of hydrolytic enzymes. Although crystalline trypsin is known to catalyze the hydrolysis of internal peptide bonds of proteins, its action toward internal peptide bondsof synthetic substrates has been demonstrated for only one ...
متن کاملThe specific esterase activity of carboxypeptidase.
It was recently found that the proteolytic enzymes trypsin (19 and chymotrypsin (2) possess specific esterase activity. In addition to catalyzing the hydrolysis of specific peptides (3-7), these enzymes also catalyze the hydrolysis of those esters which possess the structural environment of the specific peptides. In order to substantiate further the suggestion of Schwert et al. (1) that the spe...
متن کاملEsterase activity in erythroleukemia.
Specific esterase activity, a property generally ascribed to cells of granulocytic origin, was found in abnormal erythroid precursors obtained from the bone marrows of six patients with untreated erythroleukemia. These erythroblasts also showed nonspecific esterase activity. Neither specific nor nonspecific esterase activity was detected in erythroid precursors obtained from the bone marrows of...
متن کاملCharacterization of enterobacteria by esterase specific-activity profiles.
The spectrum of specific activities and the electrophoretic mobilities of esterases produced by 550 strains of Enterobacteriaceae belonging to 36 species and subclassified into six groups (group 1, Escherichia coli, Shigella and Escherichia hermanii; group 2, genus Salmonella and genus Citrobacter; group 3, genus Klebsiella and genus Enterobacter; group 4, genus Serratia and Serratia fonticola;...
متن کاملEsterase Activity in Developing Pods of Soyheans
Four stages of soybean pod development of four varieties of Glycine max were surveyed for esterase enzymes by starch-gel electrophoresis. Differences in esterase banding patterns occur among the four varieties investigated. Enzyme changes accompanying pod development were observed. Pod collection procedure affected the number of esterase bands visible, with collection in dry ice giving more vis...
