Figure 3From: Genome-wide identification of Xenopus matrix metalloproteinases: conservation and unique duplications in amphibiansComparison of Xenopus MMP3 with human MMP1, 3, and 10. Note that the shadowed region at the end of the catalytic domain corresponds to the same region in Fig. 2 except the insertion of 8–14 aa in stromelysins (MMP3, 10) compared to collagenases (e.g., the MMP1 shown here). See Fig. 2 for other information.Back to article page
