Function

CNRR_CUPMC CnrH alone is able to activate cnr expression, while both CnrY and CrnR (CnrX) are needed for nickel induction of CnrH (PubMed:10671463). Has been suggested (PubMed:10671464) to bind nickel.^[1] ^[2]

Publication Abstract from PubMed

Both the X-ray structures of the apo- and the copper-bound forms of the metal-sensor domain (residues 31-148) of CnrX from Cupriavidus metallidurans CH34 were obtained at 1.74A resolution from a selenomethionine derivative. This four-helix hooked-hairpin is the first structure of a metal-sensor in an ECF-type signaling pathway. The copper ion is bound in a type 2-like center with a 3N1O coordination in the equatorial plane and shows an unprecedented remote fifth axial ligand with Met93 contributing a weak S-Cu bond. The signal onset cannot be explained by conformational changes associated with CnrX metallation.
