Protein Expr. Purif. 1994 Feb;5(1):84-8
A proteinase was purified from the human pathogenic fungus Aspergillus fumigatus. The four chromatographic steps, a “negative” dye column, a “positive” dye column, hydroxyapatite Ultrogel, and modified TSK gel (HW 55), gave a 14% overall yield. The protein migrated as a single band on SDS-PAGE and isoelectric focusing, with an M(r) of 82,000 and a pI of 5.6. Inhibitor studies suggested that the enzyme was a metalloproteinase. It hydrolyzed phenylazobenzyloxycarbonyl-Pro-Leu-Gly-Pro-Arg and cleaved native rat type I collagen.
