Fig. 5: The PrfaH paralogs are carried by various types of plasmids.

a The distribution of PrfaH paralogs carried by different plasmid types. We totally collected 3214 plasmids carrying the NusG family protein from Genbank. These plasmids were classified using PlasmidFinder. The plasmid types were indicated by different colors. NA represents the untyped plasmids. b The locus of genes encoding PrfaH paralogs on different plasmid types. The genes encoding PrfaH paralogs were colored by red. The T4SS-associated genes were colored by blue. Green represents the genes coding type IV pili. The hns genes on IncX plasmids were colored by orange. The genes with unknown functions were not colored.
