WebOne zinc ion is coordinated by Cys96, His220, and His250, while the other is loosely chelated by His67, His69, and Cys96. This is the first example of the metal ion coordination by a cysteine residue in the superfamily. Therefore, D-aminoacylase defines a novel subset and is a mononuclear zinc metalloenzyme but containing a binuclear active site.
