Abstract
|
|
|
The crystal structure of satellite panicum mosaic virus (SPMV) has been solved
by multiple isomorphous replacement and molecular replacement and refined at 1.9
A resolution. SPMV, a T = 1 icosahedral virus, is the smallest virus structure
determined. The coat protein is an eight-stranded 'jelly roll' beta-barrel with
an amino-terminal strand that extends into the interior of the virus, presumably
interacting with the RNA. Regions of electron density on the interior of the
protein capsid may be RNA, although it is not possible to construct any detailed
model of the nucleic acid. Basic amino acid residues in contact with the nucleic
acid show a considerable degree of disorder. The carboxy-terminal strand of the
virus coat protein interacts with adjacent subunits, forming an additional
beta-strand.
