Description

Studies of icosahedrally symmetric virus coat proteins (capsids) constitute one of the developing fields in recent computational chemistry. For easier and more efficient modelling of icosahedrally symmetric capsids, we developed a new version of the molecular graphics software, RasMol, named RasMol-v by implementing new functions concerning icosahedral symmetry. The most important ones of the newly implemented commands are "copymol", "addico", and "packmol". By typing "copymol", the entire capsid structure is built using a protomer structure stored in the Protein Data Bank. This command can also build any selected protomers by writing their protomer numbers as command parameters. By typing "addico", a cage of asymmetric unit of icosahedral symmetry is shown. This command can also show all the 60 cages of asymmetric unit that enclose the entire capsid structure. By typing "packmol", the amino acid residues that are placed outside the asymmetric unit are moved into the unit by rotation with the matrices of icosahedral symmetry. The newly implemented commands can be also executed through the menu bar.
