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.
