摘要
The nucleotide sequences of fic-1 involved in the cell filamentation induced by cyclic AMP in Escherichia coli and its normal counterpart fic were analyzed. The open reading frame of both fic-1 and fic coded for 200 amino acids. The Gly at position 55 in the Fic protein was changed to Arg in the Fic-1 protein. The promoter activity of fic was confirmed by fusing fic and lacZ. The gene downstream from fic was found to be pabA (p-aminobenzoate). There is an open reading frame (ORF190) coding for 190 amino acids upstream from the fic gene. Computer-assisted analysis showed that Fic has sequence similarity with part of CDC28 of Saccharomyces cerevisiae, CDC2 of Schizosaccharomyces pombe, and FtsA of E. coli. In addition, ORF190 has sequence similarity with the cyclosporin A-binding protein cyclophilin.
