Genome sizes are indicated within brackets. The DNA repair genes identified in the genome of the three organisms are shown. Those present in more than one copy due to duplications are marked in bold (numbers in parenthesis). aalkA and ada regulatory domain genes are fused in these bacteria. bmutH, found in E. coli, is not present in these 3 genomes. c ligA corresponds to the NAD-dependent ligase and ligB to the ATP-dependent ligase (see text).
