Cytoplasmic aldehyde dehydrogenase involved in ethanol oxidation. Involved in pantothenic acid production through the conversion of 3-aminopropanal to beta-alanine, an intermediate in pantothenic acid (vitamin B5) and coenzyme A (CoA) biosynthesis. an aldehyde + H2O + NAD(+) = a carboxylate + 2 H(+) + NADH 3-aminopropanal + H2O + NAD(+) = beta-alanine + 2 H(+) + NADH Expression is under the control of MSN2 and MSN4, and is induced during diauxic shift and osmotic stress. Present with 172 molecules/cell in log phase SD medium. Belongs to the aldehyde dehydrogenase family.
