Interaction of B-DNA and Monovalent Cations: Theory and Practice in X-Ray Crystallography
… in this region is explored experimentally. Anomalous scattering is proposed as a possible method for resolving this ambiguity. To this effect, the properties of rubidium I and thallium I are compared and contrasted to each other and to other group I metals. Finally, the structures of two …

Structural and Functional Studies on the Escherichia coli Inducible Lysine Decarboxylase: Linking the Acid Stress and Stringent Responses
… A combination of heavy-atom derivatization, anomalous scattering and molecular replacement techniques were used to determine the X-ray structure and the model was refined to a resolution of 2.0 Å. The structure of LdcI revealed that the protein co-crystallized with the stringent response …

X-Ray Scattering Studies of Charge and Orbital Ordering in Transition Metal Oxides
… In both materials we demonstrate that the anomalous scattering components can result in a surprising conversion from linearly to non-linearly polarised light, through two subtly different interference processes. This is the first report of such mechanisms. By performing soft x-ray …

Structure Determination of Viscotoxin A1, Tendamistat and Tri Peptidyl peptidase-I
… der Schwefelatome per SAD ("single wavelength anomalous scattering") mit Daten von einer Drehanodenanlage gelöst. Viscotoxin A1 weist wie viele Viscotoxine die für Thionine typische Tertiärstruktur auf. Eine positiv geladene Tasche, die ein funktionell essentielles Phosphation bindet, fehlt in …

Probing the interior of an active volcano: Three-dimensional seismic tomography at Montserrat
… a geologically heterogeneous region which causes anomalous scattering of the seismic wave field. A three-dimensional seismic velocity model from first-arrival travel-time tomography delineates the high-velocity cores in greater detail and reveals a low-velocity volume at 4 to 8 km depth beneath …
