Fig. 3

Conserved sequence motifs of Rep proteins. Bacterial Rep groups are depicted in gray background. Residues are colored by their chemical properties (polar, green; basic, blue; acidic, red; hydrophobic, black; neutral, purple). The Rep groups were manually ordered according to the pairwise similarity in the aligned motifs. The HUH endonuclease and SF3 helicase domains are delineated at the top of the figure
