Cobalt in the structure of Quadruple Mutant Q92C, N146F, Y168F, I172V Type III Cat Complexed With Fusidic Acid. Crystals Grown At pH 6.3. X-Ray Data Collected At Room Temperature (pdb 1qca)

The binding sites of Cobalt atom in the structure of Quadruple Mutant Q92C, N146F, Y168F, I172V Type III Cat Complexed With Fusidic Acid. Crystals Grown At pH 6.3. X-Ray Data Collected At Room Temperature (pdb code 1qca). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 1qca structure was solved by A.G.W.LESLIE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 6.0-2.2 Space group H32 a (A) 107.810 b (A) 107.810 c (A) 124.130 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) n/a Rfree (%) n/a Cobalt Binding Sites: Cobalt binding site 1 out of 2 in 1qca Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 1qca.
