| Abstract: | Human class I alcohol dehydrogenase (alcohol:NAD+ oxidoreductase, EC 1.1.1.1; ADH) is the major enzyme involved in ethanol oxidation. Three highly homologous genes govern the synthesis of three types of subunits which form several ADH isozymes. The locus for class I ADH loci was previously assigned to q21-25 of chromosome 4 by somatic cell hybridization techniques. Analysis of grain positions by in situ hybridization of chromosomes indicated that the ADH cluster locus is on 4q21-23, probably 4q22. |
