Alignment of parE and parC gene promoters with other C. crescentus gene promoters and to the ς73 consensus recognition sequence (Fig. 6) (19). Bases matching the consensus sequence are underlined. N = any base; S = C/G; W = A/T; Y = C/T. The references for promoter sequences and transcriptional start sites are as follows: dnaA (45), dnaN and dnaX (36, 42), dnaK (1a), and gyrB (35, 36).
