Figure 3From: Degradation of small leucine-rich repeat proteoglycans by matrix metalloprotease-13: identification of a new biglycan cleavage siteBiglycan cleavage sites generated by APMA-activated MMP-13. The arrow indicates the MMP-13 cleavage site, and the broken arrow the potential secondary MMP-13 cleavage site. APMA, aminophenylmercuric acetate; MMP, matrix metalloprotease; G, glycine; V, valine.Back to article page
