Sodium in the structure of L-Aspartate Oxidase: R386L Mutant (pdb 1knr)

The binding sites of Sodium atom in the structure of L-Aspartate Oxidase: R386L Mutant (pdb code 1knr). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1knr structure was solved by R.T.BOSSI, A.MATTEVI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 40.0-2.5 Space group P41212 a (A) 73.278 b (A) 73.278 c (A) 313.933 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 25 Rfree (%) 29.5 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1knr Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1knr. 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: Tyr352, A: Thr353, A: Cys354, A: Gly355, A: Gly356, A: Gly374, A: Glu375, A: Val376, A: Ser377, A: Tyr378, A: His382, A: Glu394, A: Hoh808, conact list: Atom Atom Distance (A) Na CE2 A:Tyr352 4.64 Na CZ A:Tyr352 4.60 Na OH A:Tyr352 4.17 Na O A:Thr353 2.77 Na CB A:Thr353 4.85 Na C A:Thr353 3.97 Na O A:Cys354 3.79 Na N A:Cys354 4.62 Na C A:Cys354 3.78 Na CA A:Cys354 4.25 Na O A:Gly355 2.57 Na N A:Gly355 4.17 Na C A:Gly355 3.76 Na CA A:Gly355 4.49 Na N A:Gly356 4.77 Na CA A:Gly356 5.00 Na O A:Gly374 4.07 Na C A:Gly374 4.79 Na O A:Glu375 2.19 Na N A:Glu375 4.67 Na CB A:Glu375 4.49 Na C A:Glu375 3.12 Na CG A:Glu375 4.29 Na CA A:Glu375 3.59 Na O A:Val376 4.92 Na N A:Val376 4.25 Na C A:Val376 4.34 Na CA A:Val376 4.75 Na O A:Ser377 2.37 Na N A:Ser377 3.87 Na OG A:Ser377 4.42 Na C A:Ser377 3.55 Na CA A:Ser377 4.29 Na N A:Tyr378 4.60 Na CA A:Tyr378 4.82 Na CD2 A:His382 4.80 Na OE1 A:Glu394 4.68 Na O A:Hoh808 4.36 interactive model:
