Schematic of the genomic regions in Ca. K. stuttgartiensis and Ca. N. defluvii, which contain shared genes coding for NXR, putative cyt. bd-like oxidases and electron carriers, and proteins of unknown function. Solid lines connect genes that are the closest homologs on the basis of protein phylogeny. Their predicted functions are in boldface. Dashed lines connect similar genes that are not the closest relatives in the respective phylogenetic protein trees. Predicted CDS and connecting lines are colored according to functional classes. CDS and intergenic regions are drawn to scale.
