Sodium in the structure of Crystal Structure of Trypsin Complexed With the Bpti Variant (TYR35- >Gly) (pdb 2ftm)

The binding sites of Sodium atom in the structure of Crystal Structure of Trypsin Complexed With the Bpti Variant (TYR35- >Gly) (pdb code 2ftm). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2ftm structure was solved by W.M.HANSON, M.P.HORVATH, D.P.GOLDENBERG, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.6 Space group I222 a (A) 74.591 b (A) 81.736 c (A) 123.595 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.7 Rfree (%) 22 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2ftm Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2ftm. 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: Ala24, A: Asp71, A: Asn72, A: Glu77, A: Val154, A: Hoh348, A: Hoh582, A: Hoh627, A: Hoh698, A: Hoh770, conact list: Atom Atom Distance (A) Na CB A:Ala24 4.40 Na CB A:Asp71 4.01 Na OD2 A:Asp71 2.53 Na OD1 A:Asp71 4.71 Na CG A:Asp71 3.60 Na N A:Asn72 4.51 Na CB A:Asn72 4.51 Na OE1 A:Glu77 3.49 Na OE2 A:Glu77 2.69 Na CD A:Glu77 3.47 Na CG A:Glu77 4.93 Na CG1 A:Val154 4.14 Na O A:Hoh348 4.25 Na O A:Hoh582 4.70 Na O A:Hoh627 4.59 Na O A:Hoh698 3.35 Na O A:Hoh770 3.53 interactive model:
