Abstract

It has been shown that the Aspergillus flavus O-1 micromycete secretes a complex of at least two proteolytic enzymes. The most active enzyme was isolated via preparative isoelectric focusing and characterized as a serine proteinase with a molecular weight of 17 kDa and a pI of 7.82. The proteinase had a broad substrate specificity and was able to degrade fibrillar proteins such as collagen, elastin, and fibrin.

具有纤维蛋白活性的黄曲霉O-1微菌胞外蛋白酶的形成及性质

摘要

已经表明黄曲霉O-1 微菌分泌至少两种蛋白水解酶的复合物。活性最强的酶是通过制备等电聚焦分离出来的，其特征是一种丝氨酸蛋白酶，分子量为 17 kDa，pI 为 7.82。该蛋白酶具有广泛的底物特异性，能够降解纤维状蛋白质，如胶原蛋白、弹性蛋白和纤维蛋白。
