Sodium in the structure of Crystal Structure of Galactose Mutarotase From Lactococcus Lactis Mutant D243A Complexed With Glucose (pdb 1nss)

The binding sites of Sodium atom in the structure of Crystal Structure of Galactose Mutarotase From Lactococcus Lactis Mutant D243A Complexed With Glucose (pdb code 1nss). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1nss structure was solved by H.M.HOLDEN, J.B.THODEN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-1.9 Space group P212121 a (A) 44.900 b (A) 76.200 c (A) 210.900 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 15.7 Rfree (%) 21.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1nss Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1nss. 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: Asp7, A: Gly11, A: Ser12, A: Asp13, B: Asp7, B: Gly11, B: Ser12, B: Asp13, A: Hoh1404, A: Hoh1591, conact list: Atom Atom Distance (A) Na OD1 A:Asp7 4.71 Na O A:Gly11 4.12 Na C A:Gly11 4.95 Na O A:Ser12 4.66 Na C A:Ser12 4.81 Na N A:Asp13 4.82 Na CB A:Asp13 4.35 Na OD2 A:Asp13 2.99 Na OD1 A:Asp13 2.36 Na CG A:Asp13 2.95 Na CA A:Asp13 4.71 Na CB B:Asp7 4.94 Na CA B:Asp7 4.78 Na O B:Gly11 4.18 Na C B:Gly11 4.83 Na O B:Ser12 4.42 Na C B:Ser12 4.75 Na N B:Asp13 4.95 Na CB B:Asp13 4.56 Na OD2 B:Asp13 3.29 Na OD1 B:Asp13 2.39 Na CG B:Asp13 3.16 Na CA B:Asp13 4.84 Na O A:Hoh1404 2.48 Na O A:Hoh1591 2.47 interactive model:
