			206 genes  | 
	
		| Product | 					Type IV secretion system protein VirB11 homolog | 
		| 1stcategory | 		P-T4SS | 
			2ndcategory | 		VirB11/TrbB/GspE Family | 
		| 3rdcategory | 		Probable effector translocator | 
		| Function | 					Component of the Trw Bartonella T4S system that may be required for invasion of the erythrocytes in the mammalian host. Probably TrwD binds ATP. | 
		| Miscellaneus | 				Trw system may be recently acquired to one of the Bartonella lineages by horizontal gene transfer, followed by a functional switch from plasmid conjugation to host association.
