Type IV secretion systems: versatility and diversity in function
... Type IV secretion systems (T4SSs) are large protein complexes which traverse the cell enve- lope of many bacteria. They contain a channel through which proteins or protein–DNA complexes can be translocated. ...

Structural Insight into How Bacteria Prevent Interference between Multiple Divergent Type IV Secretion Systems
... ABSTRACT Prokaryotes use type IV secretion systems (T4SSs) to translocate substrates (e.g., nucleoprotein, DNA, and protein) and/or elaborate surface structures (i.e., pili or adhesins). Bacterial genomes ...

Recent advances in the structural and molecular biology of type IV secretion systems
... VirB3 is a small inner-membrane protein that binds to VirB4, and, intriguingly, in some T4S systems, the two are fused into a single protein [3]. Interaction of VirB3 with VirB4 might assist membrane localization ...
