Figure 5: In vitro proteolytic degradation of collagen type V by purified metalloprotease from Cryptobia salmositica. Lanes A–E: collagen incubated with metalloprotease for 0, 2, 4, 6, and 8 hours respectively; lane F: collagen incubated under same conditions as lanes A–E, but without metalloprotease (control); lane M: molecular markers (reproduced from Zuo and Woo [18]).
