MMP1 (Welgus et al. 1981), MMP8 (Hasty et al. 1987), and MMP13 (Knauper et al. 1996, Mitchell et al. 1996), called collagenases I, II and III respectively, are all able to cleave the intrahelical bonds of collagen type III, cleaving between amino acids Gly948 and Ile949 of the Uniprot canonical sequence. MMP9 (Bigg et al. Veidal et al. 2010) and MMP10 (Stromelysin-2) are able to degrade collagen type III (Nicholson et al. 1989).
