Sodium in the structure of Crystal Structure of An Engineered Ferredoxin(Flavodoxin) Nadp(H) Reductase (Fpr) From Escherichia Coli (pdb 2xnj)

The binding sites of Sodium atom in the structure of Crystal Structure of An Engineered Ferredoxin(Flavodoxin) Nadp(H) Reductase (Fpr) From Escherichia Coli (pdb code 2xnj). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2xnj structure was solved by H.BOTTI, M.A.MUSUMECI, E.A.CECCARELLI, A.BUSCHIAZZO, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 27.8-1.9 Space group C121 a (A) 186.883 b (A) 74.580 c (A) 44.421 alpha (°) 90.00 beta (°) 101.86 gamma (°) 90.00 Rfactor (%) 18.82 Rfree (%) 22.36 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2xnj Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2xnj. 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: B: Glu214, B: Hoh2072, B: Hoh2156, B: Hoh2159, B: Hoh2167, B: Hoh2168, B: Hoh2169, B: Hoh2170, B: Hoh2200, conact list: Atom Atom Distance (A) Na OE1 B:Glu214 4.24 Na OE2 B:Glu214 4.26 Na CD B:Glu214 4.66 Na O B:Hoh2072 2.30 Na O B:Hoh2156 4.95 Na O B:Hoh2159 2.30 Na O B:Hoh2167 4.24 Na O B:Hoh2168 4.19 Na O B:Hoh2169 4.39 Na O B:Hoh2170 3.56 Na O B:Hoh2200 2.23 interactive model:
