  1. *The functional classification of the B. subtilis protein-coding genes was adapted from Kunst et al. [29]. The number of sequences and of genes in each category is listed for ANU265 and B. subtilis, respectively. The percent of the putatively identified genes devoted to each functional group is indicated in brackets.
