title: Cloning and characterization of the gene for a methanol-utilising alcohol dehydrogenase from Bacillus stearothermophilus.
abstract: The cloning and characterization of the alcohol dehydrogenase (ADH) gene (adh) from Bacillus stearothermophilus strain DSM2334, an obligate aerobe, are described. The clone directed the synthesis of ADH as judged on Western blots, activity gels and tetrazolium plates. It specified an enzyme that oxidised methanol as well as ethanol. The enzyme was found to be encoded by a single gene in B. stearothermophilus which did not cross-hybridize to adh clones from Escherichia coli, yeast or maize. The cloned gene was expressed in E. coli but activity was not detected in Bacillus subtilis, despite stable maintenance of the recombinant plasmid in this host. The gene is catabolite-repressed in DSM2334.
