Organism	Agrobacterium tumefaciens C58 UWash	Cluster	68 genes
Product	Type IV secretion system protein VirB4
1stcategory	P-T4SS	2ndcategory	VirB4/TrbE/CagE Family
3rdcategory	Effector and T-DNA translocator
Function	Component of the T4SS VirB/D4 required for the translocation of the virulence factors (VirE2, VirF and the VirD2-T-DNA complex) to plant cells. VirB4 has both energetic and structural roles in substrate translocation. VirB4, VirB11 and VirD4 interact with each other, and that they promote substrate transfer by both ATP-independent and -dependent mechanisms.
Miscellaneus	The hexameric VirB4 C-terminal domain resides in the periplasm and interacts with inner membrane Virb11 and periplasmic VirB8 and VirB10. N-terminal VirB4 interacts with cytoplasmic regions of VirD4 and VirB10.
