a

Positions have been calculated between the first nucleotide of the start codon and the middle of the putative binding site.

b

Values in parentheses are not statistically significant (i.e. with FDR > 0.05).

c

See hierachical clustering analysis in Figure 8. ND, Not determined (hypothetical proteins were excluded from the analysis).

d

umuD and umuC genes are likely organized in an operon.

e

The complete open reading frame number is SynWH7803_XXXX.
