Comparison of the amino acid sequences of Homo sapiens tyrosinase (HsTyrosinase; Accession number: AAB60319) and Bacillus megaterim tyrosinase (BmTyrosinase; Accession number: ACC86108). The online CLUSTALW multiple sequence alignment software (http://www.genome.jp/tools/clustalw/) was used for the slow and accurate pairwise alignment analysis. “*,” Fully conserved residues; “:,” conserved substitutions; “.,” semi-conserved substitution as previously described (Grasela et al., 2008). Copper-binding regions A and B are underlined. The histidine residues marked with “▲” are the ligands proposed to coordinate two copper ions in the active site pocket.
