Sorbitol dehydrogenase is a zinc enzyme

J Jeffery et al. EMBO J. 1984 Feb.

Abstract

Evidence is given that tetrameric sorbitol dehydrogenase from sheep liver contains one zinc atom per subunit, most probably located at the active site, and no other specifically bound zinc or iron atom. In alcohol dehydrogenases that are structurally related to sorbitol dehydrogenase, more than one zinc atom per subunit can complicate investigations of zinc atom function. Therefore, sorbitol dehydrogenase will be particularly valuable for defining the precise roles of zinc in alcohol and polyol dehydrogenases, and for establishing correlations of structure and function with other important zinc-containing proteins.
