The Agrobacterium tumefaciens Chaperone-Like Protein, VirE1, Interacts with VirE2 at Domains Required for Single-Stranded DNA Binding and Cooperative Interaction

Agrobacterium tumefaciens transfers single-stranded DNA (ssDNA) into plants. Efficient tumorigenesis requires VirE1-dependent export of ssDNA-binding (SSB) protein VirE2. VirE1 binds VirE2 domains involved in SSB and self-association, and VirE1 may facilitate VirE2 export by preventing VirE2 aggregation and the premature binding of VirE2 to ssDNA.
