| Function | Component of a type IV secretion system (T4SS) vir homolog that plays a symbiotic role. T4SS is required for translocation of rhizobial effector proteins, such as Msi059 and Msi061 into the plant cells. Processed VirB2 may be the major component of extracellular T pilus. |
| Miscellaneus | T4SS VirB/D4 is enconded on symbiotic island. The Mesorhizobium loti strain R7A symbiosis island is a 502-kb chromosomally integrated element which transfers to nonsymbiotic mesorhizobia in the environment, converting them to Lotus symbionts. It integrates into a phenylalanine tRNA gene in a process mediated by a P4-type integrase encoded at the left end of the element.
