Laue diffraction studies of human rhinovirus 14 and canine parvovirus.
Laue diffraction data have been collected from monoclinic crystals of canine parvovirus (CPV), and from cubic crystals of human rhinovirus 14 (HRV14) with and without bound antiviral compounds. In optimal conditions one or two images of HRV14 were sufficient to calculate interpretable electron-density maps of the virus complexes at 3.5 A resolution. The crystals of CPV were of lower symmetry and were more easily damaged by radiation, making it difficult to accumulate a significant amount of useful data. Results on HRV14 are compared in studies on four antiviral compounds where data were collected using both monochromatic and Laue diffraction. Two Laue diffraction images of HRV14 with a point mutation were sufficient to determine the change from a leucine to a valine in VP2.
