Abstract
Proteolytic, arylamidase-like activities of human serum are determined by using a sensitive micromethod, based upon the Bratton-Marshall-reaction, and amino acid-p-nitroanilides as substrates. Besides the alanine-aminopeptidase and the oxytocinase, the dipeptide-aminopeptidase II, a neutral peptidase, and 6 other peptidases, not yet identified by us, are differentiated with the aid of 19 substrates, by adding 8 effectors, and by incubating the enzyme tests within the pH range 6.0 to 8.4.
摘要
采用一种基于布拉顿 - 马歇尔反应且以氨基酸对硝基苯胺为底物的灵敏微量法，测定人血清的蛋白水解、芳基酰胺酶样活性。除丙氨酸氨基肽酶和催产素酶外，借助19种底物、添加8种效应物，并在pH值6.0至8.4范围内进行酶试验，可区分出二肽氨基肽酶II（一种中性肽酶）以及另外6种我们尚未鉴定的肽酶。
