Bacterial type IV secretions systems move DNA and proteins out of a cell. Usually transfer of this DNA/proteins requires

GENERAL STRUCTURE FEATURES OF TYPE 4 SECRETION SYSTEMS
With different functions comes many variations on the structure of T4SS, however the most well understood set of structures were studied through the Gram-negative bacteria A. tumefaciens. It is called the VirB/VirD4 system.
VirB is made up of 11 different VirB proteins systhesized from the virB operon. Most T4SS have homologes of these 12 proteins (11 from VirB and 1 from VirD)
