ID 1.1.5.7 DE cyclic alcohol dehydrogenase (quinone). AN cyclic alcohol dehydrogenase. AN MCAD. CA a cyclic alcohol + a quinone = a cyclic ketone + a quinol. CC -!- This enzyme oxidizes a wide variety of cyclic alcohols. CC -!- Some minor enzyme activity is found with aliphatic secondary alcohols CC and sugar alcohols, but not primary alcohols. CC -!- The enzyme is unable to catalyze the reverse reaction of cyclic CC ketones or aldehydes to cyclic alcohols. CC -!- This enzyme differs from EC 1.1.5.5, which shows activity with CC ethanol. //
