Abstract
Novel capsomeric complexes, pentamers and hexamers were detected as chemical entities in phage Qβ. Both were composed of identical protein subunits and stabilized by intermodular disulphide bonds. Their numbers per particle were about 12 for pentamers and about 20 for hexamers—consistent with theoretical expectation from the quasi-equivalent packing of 180 identical subunits in a coat protein shell.
