Abstract
Bovine parainfluenza virus type 3 (PIV-3) has a buoyant density of 1.197. The RNA of PIV-3, like that of Sendai virus, is a single continuous chain which lacks polyadenylic acid sequences and tends to self-anneal to a marked extent. It has a sedimentation coefficient of 42S and a molecular weight of 4.5 X 10(6), being slightly smaller than Sendai virus RNA (47S, 5.3 X 10(6)). PIV-3 has 5 main structural proteins, of which 2 are glycoproteins. The molecular weights of protein 1, protein 2, protein 3, glycoprotein 1, and glycoprotein 2 were estimated to be 79,000, 68,000, 35,000, 69,000, and 55,000, respectively. Protein 2 was suggested to be nucleocapsid protein.
