Sodium in the structure of Human Dipeptidyl Peptidase IV in Complex With An Alpha Amino Acid Inhibitor (pdb 2oph)

The binding sites of Sodium atom in the structure of Human Dipeptidyl Peptidase IV in Complex With An Alpha Amino Acid Inhibitor (pdb code 2oph). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2oph structure was solved by G.SCAPIN, A.E.WEBER, J.L.DUFFY, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-2.4 Space group P212121 a (A) 117.912 b (A) 126.080 c (A) 137.114 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 2oph Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2oph. 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: Gly490, A: Leu491, A: Arg492, A: Hoh1783, conact list: Atom Atom Distance (A) Na O A:Gly490 2.45 Na C A:Gly490 3.51 Na CA A:Gly490 4.66 Na O A:Leu491 2.50 Na N A:Leu491 4.10 Na C A:Leu491 3.17 Na CA A:Leu491 3.83 Na N A:Arg492 3.97 Na CA A:Arg492 4.24 Na O A:Hoh1783 4.90 interactive model:
