Sodium in the structure of Functional Glutamate 151 to Histidine Mutant of the Aminopeptidase From Aeromonas Proteolytica. (pdb 2anp)

The binding sites of Sodium atom in the structure of Functional Glutamate 151 to Histidine Mutant of the Aminopeptidase From Aeromonas Proteolytica. (pdb code 2anp). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2anp structure was solved by K.P.BZYMEK, A.MOULIN, S.I.SWIERCZEK, D.RINGE, G.A.PETSKO, R.C.HOLZ, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 50.0-1.9 Space group P6122 a (A) 109.090 b (A) 109.090 c (A) 98.417 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 18 Rfree (%) 20.5 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2anp Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2anp.
