Arsenic in the structure of Crystal Structure of An Apag Protein (PA1934) From Pseudomonas Aeruginosa PAO1 At 1.50 A Resolution (pdb 3nrf)

The binding sites of Arsenic atom in the structure of Crystal Structure of An Apag Protein (PA1934) From Pseudomonas Aeruginosa PAO1 At 1.50 A Resolution (pdb code 3nrf). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 3nrf structure was solved by JOINT CENTER FOR STRUCTURAL GENOMICS (JCSG), with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 29.2-1.5 Space group C2221 a (A) 69.343 b (A) 96.491 c (A) 61.788 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.4 Rfree (%) 22.2 Arsenic Binding Sites: Arsenic binding site 1 out of 1 in 3nrf Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 3nrf. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Arsenic atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: B: Val71, B: Ser79, B: Arg120, B: Ser122, B: Arg124, B: Cac130, B: Hoh310, conact list: Atom Atom Distance (A) As CG1 B:Val71 5.00 As CB B:Ser79 4.91 As OG B:Ser79 4.03 As OG B:Ser79 4.88 As NH1 B:Arg120 3.92 As CB B:Ser122 4.48 As OG B:Ser122 3.83 As CB B:Arg124 4.62 As CD B:Arg124 4.41 As CG B:Arg124 4.86 As O1 B:Cac130 1.71 As O2 B:Cac130 1.75 As AS B:Cac130 0.00 As C2 B:Cac130 1.96 As C1 B:Cac130 1.92 As O B:Hoh310 4.09 interactive model:
