Nickel in the structure of Crystal Structure Of the H320Q Variant of Klebsiella Aerogenes Urease (pdb 1ejv)

The binding sites of Nickel atom in the structure of Crystal Structure Of the H320Q Variant of Klebsiella Aerogenes Urease (pdb code 1ejv). This binding sites where shown with 5.0 Angstroms radius around Nickel atom. The 1ejv structure was solved by M.A.PEARSON, I.S.PARK, R.A.SCHALLER, L.O.MICHEL, P.A.KARPLUS, R.P.HAUSINGER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-2.4 Space group I213 a (A) 170.800 b (A) 170.800 c (A) 170.800 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.1 Rfree (%) n/a Nickel Binding Sites: Nickel binding site 1 out of 2 in 1ejv Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Nickel in the PDB 1ejv.
