	| Organism | 					 Brucella suis 1330  | 
			Cluster | 					
			35 genes  | 
	
		| Product | 					Type IV secretion system protein VirB3 homolog | 
		| 1stcategory | 		P-T4SS | 
			2ndcategory | 		VirB3/TrbD Family | 
		| 3rdcategory | 		Effector translocator | 
		| Function | 					The VirB T4SS could be required for the establishment of the replication niche in the host. VirB3 may play a role during assembly of the T4SS structure.  | 
		| Miscellaneus | 				VirB system is specifically induced within macrophages by phagosome acidification. Induced at 37 degrees Celsius in minimal medium, suggesting that nutritional stress is a regulating signal.
