Rvh T4SS
(Rickettsiales vir homolog (rvh) T4SS)
Rickettsia
(R. prowazekii str. Madrid E)
All sequenced Rickettsia genomes encode a P-T4SS similar to the vir archetype of Agrobacterium tumefaciens and related systems, and this T4SS is encoded across all genomes in the rickettsial families Rickettsiaceae, Anaplasmataceae, and Midichloriaceae. Lacks a homolog of VirB5, the minor pilin subunit that is indispensable for pilus formation but not substrate transfer. A defining feature of the rvh T4SS is the proliferation of genes encoding RvhB6 proteins, which are predicted IM channel components of the VirB6/TrbL family that are required for substrate transfer in P-T4SSs. Three other components are encoded by duplicate genes within the rvh T4SS: RvhB4a and RvhB4b--homologous to VirB4 (IM ATPase), RvhB9a and RvhB9b--homologous to Vir9 (participating with VirB7 and VirB10 in the OM pore of the T4SS), two VirB8-like channel proteins, RvhB8a and RvhB8b. ...
