Schematic of the ammonia oxidation pathway genomic region as well as other AOB-related genomic features in comammox Nitrospira clade A (Ca. N. nitrificans), clade B (GWW3 bin) and selected ammonia-oxidizing bacteria (Nitrosospira multiformis and Nitrosomonas europaea). Homologous genes are connected by lines. Functions of the encoded proteins are represented by color. Parallel double lines designate a break in locus organization (other genes are in between the genes of interest). Single line designates a break probably due to contig fragmentation. Position of the blocks denotes the orientation of the coding strand (upper strands for forward; down strands for reverse)
