Sodium in the structure of Crystal Structure of Tandem Type III Fibronectin Domains From Drosophila Neuroglian At 2.0 Angstroms (pdb 1cfb)

The binding sites of Sodium atom in the structure of Crystal Structure of Tandem Type III Fibronectin Domains From Drosophila Neuroglian At 2.0 Angstroms (pdb code 1cfb). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1cfb structure was solved by A.H.HUBER, Y.E.WANG, A.J.BIEBER, P.J.BJORKMAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 5.0-2.0 Space group F432 a (A) 241.800 b (A) 241.800 c (A) 241.800 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.2 Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 1cfb Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1cfb. 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: Ser679, A: Pro680, A: Trp681, A: Glu739, A: Ile740, A: Glu741, A: His742, A: Asn743, A: Hoh7, A: Hoh19, A: Hoh39, conact list: Atom Atom Distance (A) Na O A:Ser679 4.24 Na CB A:Ser679 3.28 Na OG A:Ser679 2.14 Na C A:Ser679 3.78 Na CA A:Ser679 4.17 Na O A:Pro680 2.35 Na N A:Pro680 3.63 Na CB A:Pro680 4.52 Na CD A:Pro680 4.12 Na C A:Pro680 3.47 Na CA A:Pro680 4.06 Na N A:Trp681 4.60 Na C A:Trp681 4.77 Na O A:Trp681 4.41 Na O A:Glu739 4.57 Na O A:Ile740 2.17 Na CD1 A:Ile740 4.54 Na C A:Ile740 3.18 Na CG1 A:Ile740 4.60 Na CA A:Ile740 4.10 Na O A:Glu741 4.62 Na N A:Glu741 3.99 Na C A:Glu741 4.12 Na CA A:Glu741 4.02 Na N A:His742 4.22 Na C A:His742 4.71 Na N A:Asn743 3.64 Na CB A:Asn743 4.15 Na ND2 A:Asn743 4.28 Na OD1 A:Asn743 2.13 Na CG A:Asn743 3.30 Na CA A:Asn743 3.78 Na O A:Hoh7 2.39 Na O A:Hoh19 4.10 Na O A:Hoh39 4.29 interactive model:
