| Comment | The VirB5 protein is involved in the type IV DNA secretion systems typified by the Agrobacterium Ti plasmid vir system where it interacts with several other proteins essential for proper pilus formation [1]. VirB5 is homologous to the IncN (N-type) conjugation system protein TraC [2] as well as the P-type protein TrbJ and the F-type protein TraE [3]. |
