Formation And Properties of Extracellular Proteinase of Micromycete Aspergillus flavus O-1, Active Toward Fibrillary Proteins
It has been shown that Aspergillus flavus O-1 micromycete secretes a complex of at least two proteolytic enzymes. By preparative isoelectric focusing, the most active enzyme was isolated, which turned out to be a non-glycosylated serine proteinase with a molecular weight of 17 kDa and a pI of 7.82. Proteinase had a broad substrate specificity and was able to degrade fibrillar proteins such as collagen, elastin, and fibrin.
