The structure of cucumber mosaic virus and comparison to cowpea chlorotic mottle virus.
The structure of cucumber mosaic virus (CMV; strain Fny) has been determined to a 3.2-A resolution using X-ray crystallography. Despite the fact that CMV has only 19% capsid protein sequence identity (34% similarity) to cowpea chlorotic mottle virus (CCMV), the core structures of these two members of the Bromoviridae family are highly homologous. As suggested by a previous low-resolution struct...
متن کاملStructural rigidity in the capsid assembly of cowpea chlorotic mottle virus
The cowpea chlorotic mottle virus (CCMV) has a protein cage, or capsid, which encloses its genetic material. The structure of the capsid consists of 180 copies of a single protein that self-assemble inside a cell to form a complete capsid with icosahedral symmetry. The icosahedral surface can be naturally divided into pentagonal and hexagonal faces, and the formation of either of these faces ha...

متن کاملDeletion of highly conserved arginine-rich RNA binding motif in cowpea chlorotic mottle virus capsid protein results in virion structural alterations and RNA packaging constraints.
The N-proximal region of cowpea chlorotic mottle virus (CCMV) capsid protein (CP) contains an arginine-rich RNA binding motif (ARM) that is also found in the CPs of other members of Bromoviridae and in other RNA binding proteins such as the Tat and Rev proteins of human immunodeficiency virus. To assess the critical role played by this motif during encapsidation, a variant of CCMV RNA3 (C3) pre...
متن کاملVirion swelling is not required for cotranslational disassembly of cowpea chlorotic mottle virus in vitro.
The mechanism by which virions of cowpea chlorotic mottle virus (CCMV) disassemble and allow for translation of the virion RNA is not well understood. Previous models have suggested that virion swelling is required to expose the virion RNA for translation in a process referred to as cotranslational disassembly (M. Brisco, R. Hull, and T. M. A. Wilson, Virology 148:210-217, 1986; J. W. Roenhorst...
