Abstract

A bifunctional aldehyde/alcohol dehydrogenase gene (adhE) from Thermoanaerobacter ethanolicus JW200 was identified and cloned. To unambiguously characterize the activity of AdhE, the recombinant protein was purified. The purified AdhE exhibited high enzymatic activity attributed to aldehyde dehydrogenase (11.0+/-0.3U/mg) and low alcohol dehydrogenase activity (2.6+/-0.2U/mg). Analysis of adhE homologous expression in T. ethanolicus showed that AdhE affected ethanol production.
