Function
TRAM2_ECOLX 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. Plasmid specificity is conferred by the TraD-TraM pair (By similarity).

Publication Abstract from PubMed
The solution structure of the DNA-binding domain of the TraM protein, an essential component of the DNA transfer machinery of the conjugative resistance plasmid R1, is presented. The structure has been determined using homonuclear 2-dimensional NMR spectroscopy as well as 15N labeled heteronuclear 2- and 3-dimensional NMR spectroscopy. It turns out that the solution structure of the DNA binding domain of the TraM protein is globular and dominantly helical. The very first amino acids of the N-terminus are unstructured.
