Nucleotide sequence of the so2426 promoter region and N-terminal coding region. The transcriptional start site (+1) is indicated by arrows, and putative -10 and -35 basal promoter elements are presented in boldface and underlined. Closed circles indicate conserved residues matching a predicted Fur-binding recognition site. The annotated (original) translation start codon (M1 residue) of so2426 is shown in boldface. 5'-RACE results described here indicate that the annotated translation start codon is incorrect, and residue M11 constitutes the actual start codon. The 5'-RACE primers used to identify the transcription start site are shown in italics and underlined.
