Fig 2.
Amino acid sequence alignment of porcine, human and mouse MMP23B. Note: Shading shows identical amino acid residues among the three species. Common structural domains are underlined. The MMPs consensus zinc-binding motif, HEXGHXXGXXH, is double underlined. Potential N-linked glycosylation sites are underlined. The Flynn cleavage site is framed. The conserved pro-domain cystein residue is marked by the number 1 and the methionine residue is marked by the number 2.
