Inventory of methylotrophy and nitrogen metabolism metabolic modules.

*Numbers in parentheses correspond to numbering of metabolic modules in Figure S1 in File S1. **mxaD is only present in one copy, as part of the cluster directly downstream of mxaFJGI and is not present in strains JLW8 or 301 that are devoid of mxaFJGI. #Additional copies of pqqDE are present in this genome clustered with one of the copies of pqqA, as part of a genomic island. These are divergent and likely laterally transferred. §Two homologs of ppi are present. ¶This organism only encodes NorB (not NorD).
