Figure 1From: Expression of matrix metalloproteinase-12 in aortic dissection The domain structures of human MMP-12. The latent form of human MMP-12(top), the active form of MMP-12 with molecular weight 45 KDa (middle), and the catalytic domain of MMP-12 with molecular weight 22 KDa (bottom) are illustrated. The precise amino acid residues are known from protein sequencing.Back to article page
