protein known to be responsible for single-stranded DNA and/or NTP binding (3) are largely conserved in the B. pertussis protein.
The nucleotide sequence of the recA gene of Bordetella pertussis was determined. The ORF is 1065 base pairs long, encoding 352 amino acids. As expected from the high G+C content of the gene (64.2%), the codon usage is quite different from that of its E. coli counterpart. Underlined regions upstream from the gene delineate a potential ribosome-binding-site and, further upstream, putative -10 and -35 promoter sequences. The latter encompass a typical LexA-binding-site (boxed) with 15 out of 20 conserved base pairs with respect to the E. coli consensus for SOS genes (1). The RecA protein of B. pertussis has a deduced Mr of 37736, a value close to that of the E. coli RecA protein. Its predicted amino acid sequence is 63.1 % identical to the latter (identical amino acid residues are underlined) (2). Regions of the E. coli
