Status
Functioni
Conjugative DNA transfer (CDT) is the unidirectional transfer of ssDNA plasmid from a donor to a recipient cell. It is the central mechanism by which antibiotic resistance and virulence factors are propagated in bacterial populations. Part of the relaxosome, which facilitates a site- and strand-specific cut in the origin of transfer by TraI, at the nic site. Probably autoregulates its own expression (By similarity). Plasmid specificity is conferred by the TraD-TraM pair.By similarity1 Publication

Interactioni
Subunit structurei
Homotetramer. 2 homotetramers cooperatively bind to DNA although they do not contact each other; cooperativity is achieved by DNA kinking and unwinding. Part of the relaxosome, a complex composed of plasmid encoded TraI, TraM, TraY and host-encoded IHF which binds to the F plasmid origin of transfer (oriT) in a site- and sequence-specific manner.
Interacts with TraD.
Also interacts with TraY (By similarity).
