Sodium in the structure of Contribution Of Hydrogen Bonds to the Conformational Stability Of Human Lysozyme: Calorimetry and X-Ray Analysis of Six Ser->Ala Mutants (pdb 1b5v)

The binding sites of Sodium atom in the structure of Contribution Of Hydrogen Bonds to the Conformational Stability Of Human Lysozyme: Calorimetry and X-Ray Analysis of Six Ser->Ala Mutants (pdb code 1b5v). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1b5v structure was solved by K.TAKANO, Y.YAMAGATA, M.KUBOTA, J.FUNAHASHI, S.FUJII, K.YUTANI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 8.0-2.2 Space group P212121 a (A) 56.690 b (A) 60.790 c (A) 33.680 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 16.1 Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 1b5v Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1b5v.
