The T-pilus of Agrobacterium tumefaciens

Trends Microbiol. 2000 Aug;8(8):361-9. doi: 10.1016/s0966-842x(00)01802-3.


T-pilus biogenesis uses a conserved transmembrane nucleoprotein- and protein-transport apparatus for the transport of cyclic T-pilin subunits to the Agrobacterium cell surface. T-pilin subunits are processed from full-length VirB2 pro-pilin into a cyclized peptide, a rapid reaction that is Agrobacterium specific and can occur in the absence of Ti-plasmid genes.
