Relationship between the usages of 4 to 8 nt putative SD sequences and their aSD binding affinity in (a) B. subtilis and (b) E. coli. All SD sequences have complementarity with the aSD sequences 5′-CCUCCUUU-3′ (B. subtilis) and 5′-CCUCCUUA-3′ (E. coli). Highlighted in blue are SD sequences that complement only to the un-extended 5′-CUCCUUU-3′ (B. subtilis) and 5′-CUCCUUA-3′ (B. subtilis). Highlighted in red are SD sequences that were identified after the core aSD sequences were extended to encompass CCUCC.
