the extent of similarity is equivalent to that between other highly divergent but clearly related dehydrogenases ( two zinc-containing alcohol dehydrogenases , 25 % ; sorbitol and zinc-containing alcohol dehydrogenases , 25 % ; ribitol and non-zinc-containing alcohol dehydrogenases , 20 % ) , and suggests an ancestral relationship between glucose and ribitol dehydrogenases from different bacteria . the similarities fit into a previously suggested evolutionary scheme comprising short and long alcohol and polyol dehydrogenases , and greatly extend the former group to one composed of non-zinc-containing alcohol-polyol-glucose dehydrogenases .
