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 کاملHuman plasma and serum trypsin-like esterase activity.
A spectrophotometric method using benzoyl arginine ethyl ester (BAEE) is described for the assay of serum and plasma trypsin-like esterase activity. The method was used to find activities in serum and plasma (anticoagulated with oxalate and heparin) from 12 healthy males at 3 different reaction pH’s. The effects of calcium, oxalate, heparin, soybean trypsin inhibitor, ovomucoid, and heat on thi...
متن کاملThe kinetics of the amidase and esterase activities of trypsin.
In previous reports from this laboratory investigations of the specific esterase activity of trypsin (1) and of the detailed kinetics of the hydrolysis of specific substrates by chymotrypsin and by carboxypeptidsse have been reported (2, 3). In the present paper a reinvestigation of the kinetics of the action of trypsin on benzoyl-L-argininamide and the results of kinetic studies of the action ...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
