A putative transcriptional activator of the Crp/Fnr family from the marine cyanobacterium Synechococcus sp. WH7803
UNSPECIFIED (1996) A putative transcriptional activator of the Crp/Fnr family from the marine cyanobacterium Synechococcus sp. WH7803. JOURNAL OF APPLIED PHYCOLOGY, 8 (6). pp. 565-567. ISSN 0921-8971Full text not available from this repository.
Sequence analysis immediately downstream (3') of a genomic region of Synechococcus sp. WH7803, encoding a periplasmic phosphate-binding protein (PstS), revealed an open reading frame encoding a protein of 224 amino acids. The protein exhibited considerable sequence similarity to a family of bacterial transcriptional activators that includes Crp and Fnr and consequently the ORF is designated ptrA (putative transcriptional activator). Upstream of ptrA a 18 nucleotide sequence representing a putative Pho box was found. Homologues of the ptrA gene were detected in several other phycoerythrin-containing marine Synechococcus strains. This represents the third cyanobacterial member of this class of DNA-binding protein to be described and the first such homologue in the ecologically important marine Synechococcus group. The location of ptrA immediately downstream from pstS may implicate this protein in global phosphate regulation.
