Abstract
The composition of mengovirus virions produced by infected cells varies with the incubation temperature. Virons produced at 37.0 or 39.5 degrees contain four major polypeptides (alpha, beta, gamma, and delta) and one minor polypeptide (beta'). Virons produced at 31.5 degrees C contain two additional polypeptides (D1 and E). The virions of two temperature-sensitive (ts) and thermolabile mutants of mengovirus (ts25 and ts88) contain an increased amount of polypeptide beta', with a corresponding decrease in polypeptide beta when compared with the wild-type mengovirus.
