Following initiating proteolytic cleavage by serine proteases the Cys92-Zn2+ bond is destabilized allowing autocleavage at Thr83-Leu84, generating a 42 kDa active form of MMP1 with about 20% of the activity of the 41 kDa form (Suzuki et al. 1990). Full activation is brought about by a further cleavage at Gln99-Phe100.
