Sodium in the structure of E.Coli Methionine Aminopeptidase Transition-State Inhibitor Complex (pdb 3mat)

The binding sites of Sodium atom in the structure of E.Coli Methionine Aminopeptidase Transition-State Inhibitor Complex (pdb code 3mat). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3mat structure was solved by W.T.LOWTHER, A.M.ORVILLE, D.T.MADDEN, S.LIM, D.H.RICH, B.W.MATTHEWS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 37.8-2.0 Space group P1211 a (A) 39.297 b (A) 65.155 c (A) 51.371 alpha (°) 90.00 beta (°) 106.12 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 3mat Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3mat. 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: Ser72, A: Ile73, A: Asn74, A: Glu75, A: Val76, A: Val77, A: Ile93, A: Asn95, A: Met112, A: Ser231, A: Ala232, A: Hoh515, A: Hoh521, A: Hoh537, conact list: Atom Atom Distance (A) Na O A:Ser72 3.54 Na CB A:Ser72 4.19 Na C A:Ser72 4.01 Na CA A:Ser72 4.79 Na O A:Ile73 4.25 Na N A:Ile73 4.37 Na C A:Ile73 3.93 Na CA A:Ile73 4.39 Na O A:Asn74 3.10 Na N A:Asn74 3.85 Na C A:Asn74 3.86 Na CA A:Asn74 4.22 Na N A:Glu75 4.94 Na O A:Val76 2.70 Na N A:Val76 4.49 Na CB A:Val76 4.98 Na C A:Val76 3.90 Na CA A:Val76 4.70 Na N A:Val77 4.88 Na O A:Ile93 4.56 Na CD1 A:Ile93 4.85 Na CG1 A:Ile93 4.78 Na N A:Asn95 4.86 Na CB A:Asn95 4.84 Na CE A:Met112 4.35 Na O A:Ser231 2.54 Na N A:Ser231 4.46 Na CB A:Ser231 4.57 Na C A:Ser231 3.59 Na CA A:Ser231 4.43 Na N A:Ala232 4.47 Na CA A:Ala232 4.56 Na O A:Hoh515 4.99 Na O A:Hoh521 2.79 Na O A:Hoh537 4.52 interactive model:
