Assembly of the VirB transport complex for DNA transfer from Agrobacterium tumefaciens to plant cells

The VirB transporter is a type IV secretion system that mediates the genetic transformation of plant cells by Agrobacterium tumefaciens. Assembly of this transporter depends on, first, formation of a VirB7/B9 complex that stabilizes many of the VirB proteins, second, formation of a virulence-specifi...

Description
Summary:The VirB transporter is a type IV secretion system that mediates the genetic transformation of plant cells by Agrobacterium tumefaciens. Assembly of this transporter depends on, first, formation of a VirB7/B9 complex that stabilizes many of the VirB proteins, second, formation of a virulence-specific pilus composed primarily of VirB2 and VirB5, and, third, post-translational processing of VirB1 and VirB2.
