Sodium in the structure of Ampc Beta-Lactamase in Complex With 4-Methanesulfonylamino Benzoic Acid (pdb 2hds)

The binding sites of Sodium atom in the structure of Ampc Beta-Lactamase in Complex With 4-Methanesulfonylamino Benzoic Acid (pdb code 2hds). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2hds structure was solved by K.BABAOGLU, B.K.SHOICHET, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.2 Space group C121 a (A) 119.238 b (A) 74.764 c (A) 98.050 alpha (°) 90.00 beta (°) 115.98 gamma (°) 90.00 Rfactor (%) 10.8 Rfree (%) 12.8 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2hds Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2hds. 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: Gly214, B: Ala215, B: Leu216, B: Asp217, B: Hoh1559, B: Hoh1585, B: Hoh1618, B: Hoh1626, B: Hoh1642, B: Hoh1643, B: Hoh1695, B: Hoh1740, B: Hoh1930, conact list: Atom Atom Distance (A) Na O B:Gly214 2.86 Na N B:Gly214 4.88 Na C B:Gly214 3.85 Na CA B:Gly214 4.97 Na N B:Ala215 4.36 Na C B:Ala215 4.28 Na CA B:Ala215 4.05 Na N B:Leu216 3.80 Na C B:Leu216 4.88 Na CA B:Leu216 4.65 Na N B:Asp217 4.11 Na CB B:Asp217 4.67 Na OD2 B:Asp217 4.03 Na OD1 B:Asp217 2.82 Na CG B:Asp217 3.59 Na CA B:Asp217 4.91 Na O B:Hoh1559 2.74 Na O B:Hoh1585 2.89 Na O B:Hoh1618 4.09 Na O B:Hoh1626 2.93 Na O B:Hoh1642 4.93 Na O B:Hoh1643 2.90 Na O B:Hoh1695 4.46 Na O B:Hoh1740 4.59 Na O B:Hoh1930 4.96 interactive model:
