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.
VirB转运体是一种IV型分泌系统，介导根癌农杆菌对植物细胞的遗传转化。该转运体的组装首先依赖于形成稳定许多VirB蛋白的VirB7/B9复合物，其次依赖于形成主要由VirB2和VirB5组成的毒力特异性菌毛，第三依赖于VirB1和VirB2的翻译后加工。
