Sodium in the structure of Human Carbonic Anhydrase II Mutant K170D (pdb 3mni)

The binding sites of Sodium atom in the structure of Human Carbonic Anhydrase II Mutant K170D (pdb code 3mni). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3mni structure was solved by J.F.DOMSIC, R.MCKENNA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.8-1.8 Space group P1211 a (A) 42.599 b (A) 41.609 c (A) 72.774 alpha (°) 90.00 beta (°) 104.40 gamma (°) 90.00 Rfactor (%) 15.4 Rfree (%) 19 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3mni Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3mni. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Sodium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Asn62, A: His64, A: Asn67, A: Gln92, A: Hoh315, A: Hoh344, A: Hoh384, conact list: Atom Atom Distance (A) Na ND2 A:Asn62 3.96 Na NE2 A:His64 3.83 Na CD2 A:His64 4.99 Na CE1 A:His64 4.41 Na ND2 A:Asn67 3.80 Na OD1 A:Asn67 4.89 Na CG A:Asn67 4.79 Na NE2 A:Gln92 4.24 Na O A:Hoh315 3.71 Na O A:Hoh344 4.94 Na O A:Hoh384 4.45 interactive model:
