(biochemistry) The enzyme tyrosinase.

Crystallographic structure of a Streptomyces-derived tyrosinase in complex with a so-called "caddie protein". In all models, only the tyrosinase molecule is shown, copper atoms are shown in green and the molecular surface is shown in red. In models D and E, histidine amino acids are shown as a blue line representation. From model E, each copper atom within the active site is indeed complexed with three histidine residues, forming a type 3 copper center. From models C and D, the active site for this protein can be seen to sit within a pillus formed on the molecular surface of the molecule.

This is an alignment structure showing only the conserved region of protein nucleotide sequences of Frogs (Their NCBI GenBank accession number CAR95491, CAJ82935, BAA02077, BAV78831 and AAC17168), Snakes (Their NCBI GenBank accession numbers BBC55580, XP032076040 and BBC55647) and Human (GenBank accession number AAA61242) using Clustal Omega. (Note: (*) shows a conserved region,(.) shows more conserved and (:) shows less conserved.)
