		| 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. VirB1 is a bifunctional protein required for virT4SS assemby. The N-terminal lytic transglycosylase domain provides localized lysis of the peptidoglycan cell wall to allow insertion of the T4SS. The C-terminal VirB1* promotes T-pilus assembly through protein-protein interactions with T-pilus subunits. | 
		| Miscellaneus | 				The C-terminal third of the protein, VirB1*, is cleaved from VirB1 and secreted by an unknwon mechanism.
