Publication Abstract from PubMed
The crystal structure of Helicobacter pylori holo-NikR, a Ni(2+)-dependent transcription factor, determined at pH 7.3, shows four square-planar nickel-binding sites, involving one cysteinate and three histidine ligands. This observation reconciles previous inconsistencies among calorimetric data, structural information at non-physiological pH, and computational studies.
