Yeast alcohol dehydrogenase (EC 1.1.1.1) is a member of a large family of zinc-containing alcohol dehydrogenases. The primary structures of 47 members of this family have been determined and aligned and an evolutionary tree was constructed, assuming a divergent evolution froma common ancestral gene.1 In thisway, it was possible to identify four divergent groups of alcohol dehydrogenases (ADH) in this family: vertebrates, plants, eukaryotic microorganisms and prokaryotic bacteria. Bakers yeast (Saccharomyces cerevisiae), a member of the third group, has three isoenzymes of alcohol dehydrogenase: YADH-1, YADH-2 and YADH-3. YADH-1 is the constitutive form that is expressed during anaerobic fermentation.2 YADH-2 is another cytoplasmic form which is repressed by glucose3 and YADH-3
