Molecular Cloning of Quinohemoprotein Alcohol Dehydrogenase, ADH IIB, from Pseudomonas putida HK5

Abstract

Molecular cloning of the gene of quinohemoprotein alcohol dehydrogenase (ADH IIB) from Pseudomonas putida HK5 was done. The gene (qbdA) was 690 amino acids in length, containing a 22-amino acid signal sequence. Another gene (qbdB) upstream of qbdA, probably in the same transcriptional unit, was found. Further upstream, a gene divergently transcribed against qbdBA had identity with NAD-dependent aldehyde dehydrogenase. © 2003 by Japan Society for Bioscience, Biotechnology, and Agrochemistry.
