Chromium in the structure of Dna Polymerase Beta (Pol B) (E.C.2.7.7.7) Complexed With Seven Base Pairs Of Dna; Soaked in the Presence of CRCL3 (Saturated Solution) (pdb 1zqe)

The binding sites of Chromium atom in the structure of Dna Polymerase Beta (Pol B) (E.C.2.7.7.7) Complexed With Seven Base Pairs Of Dna; Soaked in the Presence of CRCL3 (Saturated Solution) (pdb code 1zqe). This binding sites where shown with 5.0 Angstroms radius around Chromium atom. The 1zqe structure was solved by H.PELLETIER, M.R.SAWAYA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-3.7 Space group P21212 a (A) 178.977 b (A) 57.463 c (A) 47.698 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17.1 Rfree (%) n/a Chromium Binding Sites: Chromium binding site 1 out of 2 in 1zqe Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Chromium in the PDB 1zqe.
