Abstract
The nucleotide sequence of a 4 kb fragment containing the Vibrio alginolyticus glnA, ntrB and ntrC genes was determined. The upstream region of the glnA gene contained tandem promoters. The upstream promoter resembled the consensus sequence for Escherichia coli σ70 promoters whereas the presumptive downstream promoter showed homology with nitrogen regulated promoters. Four putative NRI binding sites were located between the tandem promoters. The ntrB gene was preceded by a single presumptive NRI binding site. The ntrC gene was located 45 base pairs downstream from the ntrB gene. The V. alginolyticus ntrB and ntrC genes were able to complement ntrB, ntrC deletions in E. coli.
