^a.

Length (amino acid residues) of the respective protein from Bacillus subtilis strain 168.

^b.

Bacterial genera are abbreviated as follows: B., Bacillus; C., Clostridium; G, Geobacillus; O., Oceanobacillus., S., Symbiobacterium.

^c.

Phylogenetic distribution among spore-forming clades; ‘Bacillales’ indicates members of families Bacillaceae, Alicyclobacillaceae and Paenibacillaceae, except for B. selenitireducens and Exiguobacterium spp. (see Table 1).
