Pseudosymmetry in the structure of myohemerythrin.
The three-dimensional structure of the protein myohemerythrin from retractor muscles of the sipunculan worn Themiste zostericola has been explored for the existance of approximately symmetry operators that locally interrelate portions of the molecule. First, the electron denisty distribution at 5.5 A resolution was examined. A local 2-fold axis that transposes the C-D helix pair into the A-B he...
متن کاملStructure determination of A2M3+TaO6 and A2M3+NbO6 ordered perovskites: octahedral tilting and pseudosymmetry.
The room-temperature crystal structures of six A(2)M(3+)M(5+)O(6) ordered perovskites have been determined from neutron and X-ray powder diffraction data. Ba(2)YNbO(6) adopts the aristotype high-symmetry cubic structure (space group Fm\overline 3m, Z = 4). The symmetries of the remaining five compounds were lowered by octahedral tilting distortions. Out-of-phase rotations of the octahedra about...
متن کاملDirect-methods structure determination of a trypanosome RNA-editing substrate fragment with translational pseudosymmetry
Using direct methods starting from random phases, the crystal structure of a 32-base-pair RNA (675 non-H RNA atoms in the asymmetric unit) was determined using only the native diffraction data (resolution limit 1.05 Å) and the computer program SIR2014. The almost three helical turns of the RNA in the asymmetric unit introduced partial or imperfect translational pseudosymmetry (TPS) that modulat...
متن کاملStructure and pseudosymmetry of cholesterol at 310 K.
The structure of cholesterol above the (304.8 K) phase transition, previously published in preliminary form [Hsu & Nordman (1983). Science, 220, 604-606], has been fully refined using augmented X-ray data. The crystals are triclinic, space group P1, with (reassigned) cell parameters a = 27.565 (10), b = 38.624 (16), c = 10.748 (4) A, alpha = 93.49 (3), beta = 90.90 (3), gamma = 117.15 (3) degre...
