Sodium in the structure of Toxoplasma Gondii Apicoplast-Targeted Acyl Carrier Protein (pdb 2qnw)

The binding sites of Sodium atom in the structure of Toxoplasma Gondii Apicoplast-Targeted Acyl Carrier Protein (pdb code 2qnw). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2qnw structure was solved by V.V.LUNIN, A.WERNIMONT, J.LEW, W.QIU, L.LIN, A.HASSANALI, I.KOZIERADZKI, Y.ZHAO, M.SCHAPIRA, A.BOCHKAREV, J.WEIGELT, M.SUNDSTROM, C.H.ARROWSMITH, A.EDWARDS, R.HUI, S.BROKX, STRUCTURAL GENOMICS CONSORTIUM (SGC), with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 34.9-1.9 Space group P3121 a (A) 38.814 b (A) 38.814 c (A) 104.617 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 17.2 Rfree (%) 23 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2qnw Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2qnw.
