The binding sites of Mercury atom in the structure of Carbonic Anhydrase II (F131V) Complexed With 4- (Aminosulfonyl)-N-[(2,4-Difluorophenyl)Methyl]-Benzamide (pdb code 1i9m). This binding sites where shown with 5.0 Angstroms radius around Mercury atom.
The 1i9m structure was solved by C.-Y.KIM, P.P.CHANDRA, A.JAIN, D.W.CHRISTIANSON, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
