Bromine in the structure of Crystal Structure Analysis of A 26MER Rna Molecule, Representing A New Rna Motif, the Hook-Turn (pdb 1mhk)

The binding sites of Bromine atom in the structure of Crystal Structure Analysis of A 26MER Rna Molecule, Representing A New Rna Motif, the Hook-Turn (pdb code 1mhk). This binding sites where shown with 5.0 Angstroms radius around Bromine atom. The 1mhk structure was solved by S.SZEP, J.WANG, P.B.MOORE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 15.0-2.5 Space group C121 a (A) 30.169 b (A) 62.510 c (A) 50.933 alpha (°) 90.00 beta (°) 98.76 gamma (°) 90.00 Rfactor (%) 23.9 Rfree (%) 27 Bromine Binding Sites: Bromine binding site 1 out of 1 in 1mhk Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Bromine in the PDB 1mhk. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Bromine atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: S: A3, S: U4, conact list: Atom Atom Distance (A) Br N9 S:A3 4.06 Br C3' S:A3 4.22 Br C8 S:A3 3.46 Br C6 S:A3 4.94 Br C5 S:A3 4.10 Br C1' S:A3 4.84 Br P S:A3 4.92 Br N7 S:A3 3.50 Br O3' S:A3 4.97 Br C4 S:A3 4.42 Br OP2 S:A3 4.25 Br C2' S:A3 4.66 Br O5' S:A3 4.22 Br N3 S:U4 4.11 Br C2 S:U4 4.69 Br C6 S:U4 2.81 Br N1 S:U4 4.12 Br C5 S:U4 1.87 Br P S:U4 4.66 Br C4 S:U4 2.87 Br OP2 S:U4 3.69 Br O5' S:U4 4.60 Br O4 S:U4 3.13 interactive model:
