		| 1stcategory | 		P-T4SS | 
			2ndcategory | 		VirB4/TrbE/CagE Family | 
		| 3rdcategory | 		Probable conjugation | 
		| Function | 					Component of the T4SS VirB/D4 encoded in the plasmid pRL7, which may be required for conjugal transfer of the plasmid. | 
		| Miscellaneus | 				R.leguminosarum biovar viciae (Rlv) strain 3841 (a spontaneous streptomycin-resistant mutant of field isolate 300) has six large plasmids; pRL10 is the pSym (symbiosis plasmid) and pRL7 and pRL8 are transferable by conjugation.
