CC -!- FUNCTION: Conjugative DNA transfer (CDT) is the unidirectional transfer
CC of ssDNA plasmid from a donor to a recipient cell. It is the central
CC mechanism by which antibiotic resistance and virulence factors are
CC propagated in bacterial populations. Part of the relaxosome, which
CC facilitates a site- and strand-specific cut in the origin of transfer
CC by TraI, at the nic site. Probably autoregulates its own expression.
CC Plasmid specificity is conferred by the TraD-TraM pair (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Homotetramer. 2 homotetramers cooperatively bind to DNA
CC although they do not contact each other; cooperativity is achieved by
CC DNA kinking and unwinding. Part of the relaxosome, a complex composed
CC of plasmid encoded TraI, TraM, TraY and host-encoded IHF which binds to
CC the F plasmid origin of transfer (oriT) in a site- and sequence-
CC specific manner. Interacts with TraD. Also interacts with TraY (By
CC similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the relaxosome TraM family. {ECO:0000305}.
