Abstract

The gene encoding the valine-resistant and FAD-independent acetolactate synthase of Klebsiella pneumoniae was isolated and expressed in Escherichia coli. The nucleotide sequence of this gene was determined and it exhibited an open reading frame of 1680 bp in length. In vivo expression of the acetolactate synthase-encoding gene in E. coli revealed a single 60-kDa protein which is consistent with the molecular weight calculated from the deduced amino acid sequence of the gene product. The gene product shares about 20-30% homology with the acetolactate synthases of E. coli, yeast and higher plants.
