We have crystallized Nodamura virus, a T = 3 icosahedral virus that can infect both mammalian and insect hosts. Crystals are monoclinic, with two crystallographically independent virus molecules per asymmetric unit. Packing analysis reveals a pseudo-rhombohedral (pseudo-C2 in the monoclinic setting) arrangement of virus particles in the crystal lattice. Crystals differ from the R32 symmetry by rotational and translational deviations. The rhombohedral packing arrangement and its failure to describe the exact virus packing is analyzed in detail. The icosahedral threefold axis is rotated from the body diagonal of the pseudo-rhombohedral cell, breaking the rhombohedral symmetry. The C2 pseudo-symmetry breaks down rotationally and/or translationally.
053ChemInform Abstract The structure of the title complex (space group P21/c, Z=4) is determined in order to obtain more insight into the steric requirements posed by the phenyl groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
