CC   -!- FUNCTION: Cysteine protease able to cleave elastin, insulin, myoglobin,
CC       fibronectin, fibrinogen, HMW-kininogen, alpha-1-protease inhibitor and
CC       alpha-1-antitrypsin. Along with other extracellular proteases may
CC       contribute to the colonization and infection of human tissues (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted, cell wall. Secreted {ECO:0000250}.
CC   -!- PTM: Proteolytically cleaved. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase C47 family. {ECO:0000305}.
