Acts as a true collagenase, which is highly active and cleaves natively folded collagen. In vitro, can also cleave gelatin and the synthetic peptide FALGPA (furylacryloyl-Leu-Gly-Pro-Ala). Causes damage on dermal collagen (COL), resulting in gaps in the tissue, which might lead to an accelerated bacterial infiltration and penetration into deeper sites of the host
