Abstract

The gene adh-hT encoding a thermostable and thermophilic NAD+-dependent alcohol dehydrogenase (ADH) from the novel and more thermophilic Bacillus stearothermophilus LLD-R strain was cloned and its nucleotide sequence determined. The deduced protein sequence shows remarkable amino acid substitutions when compared to the sequence of the protein isolated from strain NCAl503 and significant similarity with the highly thermostable ADH from the thermoacidophilic archaebacterium Sulfolobus solfataricus. The alignment of these sequences led to the identification of three amino acid replacements probably responsible for the higher thermostability of the novel bacillar ADH. Adh-hT gene expression in Escherichia coli, a fast purification procedure and the characterization of the recombinant enzyme are also described
