Agrobacterium Delivers Anchorage Protein VirE3 for Companion VirE2 to Aggregate at Host Entry Sites for T-DNA Protection (Cell Reports)

Agrobacterium transfers T-DNA and virulence proteins into host cells. Li et al. show that a virulence protein, VirE3, anchors its companion protein VirE2 on host membranes at the entrance to facilitate T-DNA protection. VirE3 represents a class of proteins, anchorage proteins, which are present only in agrobacteria and rhizobia.
