Figure 1From: Genome-wide identification of Xenopus matrix metalloproteinases: conservation and unique duplications in amphibiansPhylogenetic tree of X. tropicalis (Xt) and human MMPs. Also included are chicken MMP22 (cMMP22) and Rana catesbeiana MMP1 (Rc-MMP1) as MMP22 was not found in human and Xenopus and Rc-MMP1 has a unique sequence organization (see description on MMP1). Novel X. tropicalis MMPs are highlighted in bold.Back to article page
