Abstract:TOPOS software has been applied for searching for topological types of viral capsids-virus shells generated by self assembly of proteins into geometrically ordered structure (VIPERdb database). Three topo logical capsid types that characterize packing of capsomeres (1) in the form of 12 vertex icosahedron (its ver tex are occupied with pentamers), (2) in the form of 32 vertex polyhedron (12 pentamers + 20 hexamers), and (3) in the form of 62 vertex polyhedron (12 pentamers + 50 hexamers) have been outlined.

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.
