Cobalt in the structure of Crystallographic Analysis of Upper Axial Ligand Substitutions in Cobalamin Bound to Transcobalamin (pdb 2v3n)

The binding sites of Cobalt atom in the structure of Crystallographic Analysis of Upper Axial Ligand Substitutions in Cobalamin Bound to Transcobalamin (pdb code 2v3n). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 2v3n structure was solved by J.WUERGES, S.GEREMIA, L.RANDACCIO, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.7-2.7 Space group P3121 a (A) 100.830 b (A) 100.830 c (A) 130.215 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 21.1 Rfree (%) 25.1 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 2v3n Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 2v3n. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Cobalt atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: B121001, A: Cyn1002, conact list: Atom Atom Distance (A) Co C9B A:B121001 3.16 Co C18 A:B121001 4.11 Co C11 A:B121001 2.84 Co C1 A:B121001 2.88 Co C8 A:B121001 4.15 Co C2 A:B121001 4.06 Co C4B A:B121001 3.62 Co N22 A:B121001 1.91 Co C35 A:B121001 4.78 Co C17 A:B121001 4.20 Co N21 A:B121001 1.86 Co C12 A:B121001 4.18 Co C19 A:B121001 2.84 Co C41 A:B121001 4.84 Co CO A:B121001 0.00 Co N1B A:B121001 4.30 Co C15 A:B121001 3.35 Co C37 A:B121001 4.99 Co C8B A:B121001 4.32 Co C47 A:B121001 4.82 Co C16 A:B121001 2.92 Co C6 A:B121001 2.97 Co C5 A:B121001 3.32 Co C4 A:B121001 2.87 Co C10 A:B121001 3.17 Co C13 A:B121001 4.22 Co C2B A:B121001 3.09 Co C20 A:B121001 3.59 Co C48 A:B121001 4.98 Co N3B A:B121001 2.10 Co C9 A:B121001 2.84 Co C14 A:B121001 2.96 Co N24 A:B121001 1.88 Co N23 A:B121001 1.92 Co C7 A:B121001 4.27 Co C53 A:B121001 4.86 Co C3 A:B121001 4.15 Co C26 A:B121001 4.40 Co N A:Cyn1002 3.06 Co C A:Cyn1002 1.89 interactive model:
