Abstract
VirD4 is an ATPase that selects proteins to be secreted in most T4SSs. We have shown that VirD4 from Xac recognizes conserved domains called XVIPCD found at the C-termini of X-Tfes (Alegria et al., 2005). We are interested in understanding the structure of the VirD4-XVIPCD complex, how the complex is transfered to the rest of the T4SS machinery and the nature of the role played by ATP bin…
