Potassium in the structure of Sulfite Reductase Structure Reduced With Crii Edta, 5-Coordinate Siroheme, Siroheme Feii, [4FE-4S] +1 (pdb 5aop)

The binding sites of Potassium atom in the structure of Sulfite Reductase Structure Reduced With Crii Edta, 5-Coordinate Siroheme, Siroheme Feii, [4FE-4S] +1 (pdb code 5aop). This binding sites where shown with 5.0 Angstroms radius around Potassium atom. The 5aop structure was solved by B.R.CRANE, E.D.GETZOFF, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-2.2 Space group P212121 a (A) 69.800 b (A) 77.400 c (A) 87.800 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 16.4 Rfree (%) n/a Potassium Binding Sites: Potassium binding site 1 out of 1 in 5aop Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Potassium in the PDB 5aop. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Potassium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Phe361, A: Ile362, A: Glu363, A: Asn364, A: Gly365, A: Asn395, A: Gln396, A: Asn397, A: Hoh631, A: Hoh639, A: Hoh765, conact list: Atom Atom Distance (A) K CD1 A:Phe361 4.20 K CZ A:Phe361 4.81 K CE1 A:Phe361 4.00 K O A:Ile362 2.62 K N A:Ile362 4.16 K C A:Ile362 3.63 K CA A:Ile362 4.49 K N A:Glu363 4.43 K C A:Glu363 4.67 K CA A:Glu363 4.48 K N A:Asn364 4.16 K C A:Asn364 4.98 K CA A:Asn364 4.90 K N A:Gly365 4.29 K CA A:Gly365 5.00 K O A:Asn395 2.86 K C A:Asn395 4.01 K O A:Gln396 3.38 K N A:Gln396 4.58 K OE1 A:Gln396 4.44 K CB A:Gln396 3.94 K C A:Gln396 3.69 K CA A:Gln396 4.24 K N A:Asn397 4.25 K CB A:Asn397 4.60 K ND2 A:Asn397 3.70 K OD1 A:Asn397 2.83 K CG A:Asn397 3.45 K CA A:Asn397 4.58 K O A:Hoh631 3.26 K O A:Hoh639 3.17 K O A:Hoh765 2.84 interactive model:
