Figure 2. Genetic organization of genome and plasmid encoded GGI-like T4SSs identified in α-, β-, and γ-proteobacteria.

The official numbering and nomenclature of the genes is indicated within the gene-arrows. The corresponding homologues are indicated on top of the arrows. T4SS genes are indicated by coloring, homologous genes are labeled in equivalent colors. The lengths of the arrows correspond to the lengths of the annotated genes. A scale bar of 3 kb is given on the right bottom of the schematic.
