site_idACA
Number of Residues7
DetailsTHE COPPER ATOM IN THE ACTIVE SITE OF EACH SUBUNIT IS LIGATED TO THREE HISTIDINE RESIDUES AND TWO WATER MOLECULES IN A DISTORTED SQUARE PYRAMIDAL ARRANGEMENT. THE ORGANIC COFACTOR TOPA QUINONE (TPQ) IS IN THE ACTIVE SITE WITH THE NEAREST QUINONE OXYGEN ATOM AT ~6A FROM THE COPPER ATOM.
