Copper in the structure of Crystal Structure of An Electron Transfer Complex Between Aromatic Amine Dephydrogenase and Azurin From Alcaligenes Faecalis (Form 2) (pdb 2iaa)

The binding sites of Copper atom in the structure of Crystal Structure of An Electron Transfer Complex Between Aromatic Amine Dephydrogenase and Azurin From Alcaligenes Faecalis (Form 2) (pdb code 2iaa). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 2iaa structure was solved by N.SUKUMAR, Z.CHEN, D.LEYS, N.S.SCRUTTON, D.FERRATI, A.MERLI, G.L.ROSSI, H.D.BELLAMY, A.CHISTOSERDOV, V.L.DAVIDSON, F.S.MATHEWS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 47.0-1.9 Space group P212121 a (A) 67.216 b (A) 131.722 c (A) 133.204 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17.4 Rfree (%) 20.5 Copper Binding Sites: Copper binding site 1 out of 1 in 2iaa Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 2iaa.
