The soluble fraction of a cell extract of Saccharomyces cerevisiae was found to contain hydrolytic activity toward arginyl-arginyl-β-naphthylamide (Arg-Arg-βNA). Most of the contaminating Arg-βNA hydrolysis activity was removed by diethylaminoethyl (DEAE)-cellulose column chromatography and the enzyme was partially purified. It is very similar in various properties to mammalian dipeptidyl aminopeptidase III (DAP III), although it differs slightly in some respects.
研究发现,酿酒酵母细胞提取物的可溶性部分含有对精氨酰-精氨酰-β-萘甲酰胺(Arg-Arg-βNA)的水解活性。通过二乙氨基乙基(DEAE)-纤维素柱层析法去除了大部分污染性 Arg-βNA 水解活性,并部分纯化了该酶。它的各种特性与哺乳动物的二肽基氨基肽酶 III(DAP III)非常相似,但在某些方面略有不同。
