  1. E-box hits are the 500 highest scoring motif matches in promoters from -200 to -20 from the translation start codon. Percent values based on zero or one hit are in parentheses to indicate high uncertainty. The uncorrected P-value shown was determined by comparison with the number of hits in all promoters (Fisher's exact test for small families and the χ-square approximation for large families). After Bonferoni correction for multiple testing the sru and srw P-values are not significant. The str and srj families are closely related and were analyzed together. A few small chemoreceptor families are not shown individually, so numbers shown do not add up to the SR total. SR, all members of putative chemoreceptor families; NA, not applicable; NS, not significant.
