Copper in the structure of Structure of Apo-Azurin From Alcaligenes Denitrificans At 1.8 Angstroms Resolution (pdb 1azc)

The binding sites of Copper atom in the structure of Structure of Apo-Azurin From Alcaligenes Denitrificans At 1.8 Angstroms Resolution (pdb code 1azc). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1azc structure was solved by E.N.BAKER, W.E.B.SHEPARD, R.L.KINGSTON, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-1.8 Space group C2221 a (A) 75.100 b (A) 74.100 c (A) 99.500 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 2 in 1azc Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1azc.
