NMR resonance assignments of NarE, a putative ADP-ribosylating toxin from Neisseria meningitidis
Abstract
NarE is a 16 kDa protein identified from Neisseria meningitidis, one of the bacterial pathogens responsible for meningitis. NarE belongs to the ADP-ribosyltransferase family and catalyses the transfer of ADP-ribose moieties to arginine residues in target protein acceptors. Many pathogenic bacteria utilize ADP-ribosylating toxins to modify and alter essential functions of eukaryotic cells. NarE was proposed to bind iron through a Fe-S center which is supposed to be implied in catalysis. We have produced and purified uniformly labeled (15)N- and (15)N/(13)C-NarE and assigned backbone and side-chain resonances using multidimensional heteronuclear NMR spectroscopy. These assignments provide the starting point for the three-dimensional structure determination of NarE and the characterization of the role of the Fe-S center in the catalytic mechanism.
