Function
ADH1_ENTH1 Alcohol dehydrogenase with a preference for medium chain secondary alcohols, such as 2-butanol and isopropanol. Has very low activity with primary alcohols, such as ethanol. Under physiological conditions, the enzyme reduces aldehydes and 2-ketones to produce secondary alcohols. Is also active with acetaldehyde and propionaldehyde.[1]

Publication Abstract from PubMed
The structure of the apo form of alcohol dehydrogenase from a single-cell eukaryotic source, Entamoeba histolytica, has been determined at 1.8 A. To date, bacterial and archeal alcohol dehydrogenases, which are biologically active as tetramers, have crystallized with tetramers in the asymmetric unit. However, the current structure has one independent dimer per asymmetric unit and the full tetramer is generated by application of the crystallographic twofold symmetry element. This structure reveals that many of the crystallization and cryoprotection components, such as cacodylate, ethylene glycol, zinc ions and acetate, have been incorporated. These crystallization solution elements are found within the molecule and at the packing interfaces as an integral part of the three-dimensional arrangements of the tetramers. In addition, an unexpected modification of aspartic acid to O-carboxysulfanyl-4-oxo-L-homoserine was found at residue 245.
