Molecular cloning of a full-length cDNA for human alcohol dehydrogenase.


We have cloned a full-length cDNA coding for human alcohol dehydrogenase (ADH; alcohol:NAD+ oxidoreductase, EC from a human liver cDNA library constructed in phage lambda gt11. The library was screened by using a rabbit antibody against human ADH as a first probe, by the modified method of Young and Davis [Young, R. A. & Davis, R. W. (1983) Proc. Natl. Acad. Sci. USA 80, 1194-1198]. Mixed 14-mer synthetic oligonucleotides encoding Asp-Asp-His-Val-Val and Gln-Cys-Gly-Lys-Cys were used as a second probe. These amino acid sequences are considered to be common in all three subunits (alpha, beta, and gamma) controlled by the ADH1, ADH2, and ADH3 loci. Ten lambda gt11 recombinants of 35 positive plaques obtained by antibody screening contained inserted cDNAs of 1.5-2.4 kilobase pairs and were found to exhibit positive signals by hybridization with synthetic probes. One of them, with an inserted cDNA of 1631 base pairs, contained a sequence that encodes 374 amino acid residues of the human beta 1 subunit, a chain initiation codon, a chain termination codon, and additional 3' and 5' untranslated regions. A complete amino acid sequence of the human beta 1 subunit was deduced from the cDNA.
