Fig. 1

Schematic comparison of the 33G and 33G-like cps loci. Shading indicates DNA sequence identity (%). The light grey cross indicates a related sequence between orf1 and wzx, which may be a remnant of the recombination event that gave rise to the 33G cps locus. Image was created using Easyfig version 2.2.5 [28]. For full DNA sequence alignments, see Supplementary Figs. 1 and 2
