title: Regulatory region with putA gene of proline dehydrogenase that links to the lum and the lux operons in Photobacterium leiognathi.
abstract: Nucleotide sequence of regulatory region (R & R) with putA gene (EMBL Accession No. U39227) from Photobacterium leiognathi PL741 has been determined, and the putA gene encoded amino acid sequence of proline dehydrogenase is deduced. Alignment and comparison of proline dehydrogenase of P. leiognathi with the proline dehydrogenase domain in the PutA protein of Escherichia coli and Salmonella typhimurium show that they are homologous. Nucleotide sequence reveals that regulatory region with the putA gene is linked to the lum and lux operons in genome; the gene order is <--putA--R & R(I)<--ter-lumQ-lumP-R & R-luxC-luxD-luxA-luxB-luxE--> (R & R: regulatory region; ter:transcriptional terminator), whereas the R & R is the regulatory region for the lum and the lux operons, ter is the transcriptional terminator for the lum operon, and R & R(I) apparently is the regulatory region for the putA and related genes. Nucleotide sequence analysis illustrates the specific inverted repeat (SIR), cAMP-CRP consensus sequence, canonical -10/-35 promoter, putative operator and Shine-Dalgarno (SD) sequence on the regulatory region R & R(I) for the putA and related genes; it suggests that the putA and related genes are simply linked to the lum and the lux operons in genome, the regulatory region R & R(I) is independent for the putA and related genes.
