Comments "The Cowpea Chlorotic Mottle Virus (CCMV) is an example of...a defined biological system (ref 10). It consists of 180 identical capsid proteins, which self-assemble around the central RNA yielding highly defined icosahedral virions of 28 nm in size. The icosahedral shape can be described according to the Caspar and Klug T (triangulation) number as a T=3 particle (refs 11,12). The capsid has a positively charged interior with a diameter of 18 nm, likely interacting with the RNA to stabilize the capsid structure."
