abstract = {Untreatable bacterial infections caused by a perpetual
increase of antibiotic resistant strains represent a serious
threat to human healthcare in the 21st century. Conjugative
DNA transfer is the most important mechanism for antibiotic
resistance and virulence gene dissemination among bacteria
and is mediated by a protein complex, known as type IV
secretion system (T4SS). The core of the T4SS is a
multiprotein complex that spans the bacterial envelope as a
channel for macromolecular secretion. We report the NMR
structure and functional characterization of the transfer
protein TraH encoded by the conjugative Gram-positive
broad-host range plasmid pIP501. The structure exhibits a
striking similarity to VirB8 proteins of Gram-negative
secretion systems where they play an essential role in the
scaffold of the secretion machinery. Considering TraM as the
first VirB8-like protein discovered in pIP501, TraH
represents the second protein affiliated with this family in
the respective transfer operon. A markerless traH deletion
in pIP501 resulted in a total loss of transfer in
Enterococcus faecalis as compared with the pIP501 wild type
(wt) plasmid, demonstrating that TraH is essential for
pIP501 mediated conjugation. Moreover, oligomerization state
and topology of TraH in the native membrane were determined
providing insights in molecular organization of a
Gram-positive T4SS.},
