... assembly. In the first model, both hydrophobic translocators exist in oligomeric form, with the major partner insertedstably into the membrane, whereas the minor protein is the link with the V antigen. ... stoichiometry in other species still awaits further study. The hydrophilic translocator: the V antigen The third component of the translocation apparatus isa hydrophilic protein: PcrV in P. aeruginosa, ... Yer-sinia, the increased synthesis of LcrV triggered by the activation of the system leads to the titration of LcrG,which binds LcrV in a 1 : 1 complex. In turn, thisresults in a release of the...
