Figure 10From: Fused eco29kIR- and Mgenes coding for a fully functional hybrid polypeptide as a model of molecular evolution of restriction-modification systemsA scheme of alignment for M.SsoII and M.NlaX. Identical amino acids are marked by black and similar amino acids by grey background. The figure demonstrates presence of 70 aa N-terminal domain in M.SsoII, but not in M.NlaX.Back to article page
