Pairwise sequence alignment of upstream regions of the predicted HcpR-regulated operons from Desulfovibrio species. (a) sat; (b) apsAB; (c) 206515-206516. Candidate HcpR sites are highlighted in gray. Predicted SD-boxes and start codons of the first genes in the operons are in bold. Predicted '-10' and '-35' promoter boxes are underlined. *Conserved position of alignment. See Figure 1 legend for abbreviations.
