B. coahuilensis lacks many of the genes coding for enzymes involved in nitrogen metabolism. Hidden Markov models for the bacterial enzymes involved in N2 metabolism were constructed to detect these genes in all of the sequenced Bacillus spp. Bars in different colors denote the presence of a gene predicted to code for a given enzyme.
