1H, 15N and 13C chemical shift assignment of the Gram-positive conjugative transfer protein TraHpIP501.

Conjugative transfer of DNA represents the most important transmission pathway in terms of antibiotic resistance and virulence gene dissemination among bacteria. TraH is a putative transfer protein of the type IV secretion system (T4SS) encoded by the Gram-positive (G+) conjugative plasmid pIP501. This molecular machine involves a multi-protein core complex spanning the bacterial envelope thereby serving as a macromolecular secretion channel. Here, we report the near complete (1)H, (13)C and (15)N resonance assignment of a soluble TraH variant comprising the C-terminal domain.
