Copper in the structure of Structure of Alcaligenes Faecalis Nitrite Reductase Mutant M150E That Contains Zinc (pdb 1ntd)

The binding sites of Copper atom in the structure of Structure of Alcaligenes Faecalis Nitrite Reductase Mutant M150E That Contains Zinc (pdb code 1ntd). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1ntd structure was solved by M.E.P.MURPHY, E.T.ADMAN, S.TURLEY, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-2.3 Space group H3 a (A) 127.760 b (A) 127.760 c (A) 67.020 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 17.2 Rfree (%) 23.2 Copper Binding Sites: Copper binding site 1 out of 2 in 1ntd Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1ntd.
