Crystallization and first data collection of the putative transfer protein TraN from the Gram-positive conjugative plasmid pIP501.

ABSTRACT: Conjugative plasmid transfer is the most important route for the spread of resistance and virulence genes among bacteria. Consequently, bacteria carrying conjugative plasmids are a substantial threat to human health, especially hospitalized patients. Whilst detailed information about the process has been obtained for Gram-negative type-4 secretion systems, little is known about the corresponding mechanisms in Gram-positive (G+) bacteria. The successful purification and crystallization of the putative transfer protein TraN from the G+ conjugative model plasmid pIP501 of Enterococcus faecalis are presented. Native crystals diffracted to 1.8 Å resolution on a synchrotron beamline. The crystals belonged to space group P2(1), with unit-cell parameters a=32.88, b=54.94, c=57.71 Å, β=91.89° and t
