Structural heterogeneity in protein crystals.
Extensive conformational heterogeneity is reported in highly refined crystallographic models for the proteins crambin, erabutoxin, myohemerythrin, and lamprey hemoglobin. From 6% to 13% of the amino acid side chains of these four proteins are seen in multiple, discrete conformations. Most common are flexible side chains on the molecular surface, but structural heterogeneity occasionally extends...
متن کاملStructural, Optical and Defect State Analyses of ZnO Nanoparticle Films
Synthesis of ZnO nanostructures films by a co-precipitation followed by the deposition processed onto a glass substrate by spin-coating technique was carried out. The effect of annealing temperatures (from 250 to 325 °C for 30 min) on the structural and optical properties of the ZnO films have been investigated. The structural studies reveal that ZnO films are polycrystalline with hexagonal wur...
متن کاملPhysical and structural studies on the cryocooling of insulin crystals.
Reflection profiles were analyzed from microgravity-grown ( micro g) and earth-grown insulin crystals to measure mosaicity (eta) and to reveal mosaic domain structure and composition. The effects of cryocooling on single-domain and multi-domain crystals were compared. The effects of cryocooling on insulin structure were also re-examined. Microgravity crystals were of larger volume, were more ho...
متن کاملStructural basis for bending of organic crystals.
Bending is observed in organic crystals when the packing is anisotropic in such a way that strong and weak interaction patterns occur in nearly perpendicular directions.
متن کاملExploring structural phase transitions of ion crystals
Phase transitions have been a research focus in many-body physics over past decades. Cold ions, under strong Coulomb repulsion, provide a repealing paradigm of exploring phase transitions in stable confinement by electromagnetic field. We demonstrate various conformations of up to sixteen laser-cooled (40)Ca(+) ion crystals in a home-built surface-electrode trap, where besides the usually menti...
