Arsenic in the structure of Bovine Endothelial Nitric Oxide Synthase Heme Domain Complexed With L- Arg and No(H4B-Free) (pdb 1foo)

The binding sites of Arsenic atom in the structure of Bovine Endothelial Nitric Oxide Synthase Heme Domain Complexed With L- Arg and No(H4B-Free) (pdb code 1foo). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 1foo structure was solved by C.S.RAMAN, H.LI, P.MARTASEK, B.S.S.MASTERS, T.L.POULOS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 36.5-2.0 Space group P212121 a (A) 58.206 b (A) 106.555 c (A) 156.671 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 22.3 Rfree (%) 25.3 Arsenic Binding Sites: Arsenic binding site 1 out of 2 in 1foo Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 1foo.
