Calcium in the structure of Structure of the Hemagglutinin-Neuraminidase From Human Parainfluenza Virus Type III (pdb 1v3b)

The binding sites of Calcium atom in the structure of Structure of the Hemagglutinin-Neuraminidase From Human Parainfluenza Virus Type III (pdb code 1v3b). This binding sites where shown with 5.0 Angstroms radius around Calcium atom. The 1v3b structure was solved by M.C.LAWRENCE, N.A.BORG, V.A.STRELTSOV, P.A.PILLING, V.C.EPA, J.N.VARGHESE, J.L.MCKIMM-BRESCHKIN, P.M.COLMAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 26.5-2.0 Space group P6222 a (A) 219.142 b (A) 219.142 c (A) 109.379 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 18.2 Rfree (%) 21.5 Calcium Binding Sites: Calcium binding site 1 out of 2 in 1v3b Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Calcium in the PDB 1v3b.
