MEGAN analysis of monoxide dehydrogenase.
CoxM: aerobic-type carbon monoxide dehydrogenase, middle subunit CoxM/CutM homologs; CoxL: aerobic-type carbon monoxide dehydrogenase, large subunit CoxL/CutL homologs; CoxS: aerobic-type carbon monoxide dehydrogenase, small subunit CoxS/CutS homologs. The size of the circle is relative to the number of genes assigned to each node (also indicated in numbers) and taxonomy is displayed with the lowest level predicted.
