COUPLING OF TRANSCRIPTION FROM INFLUENZA VIRIONS TO TRANSLATION INVITRO

The optimum conditions for the coupling of fowl plague virus (FPV) transcription to an in vitro reticulocyte translation system have been established and shown to be close to those required for maximum RNA synthesis by purified FPV virions. Products have been characterized by the peptides they yield on limited proteolysis in SDS and it has been shown that virus nucleoprotein (NP) and matrix (M) protein are made. The smallest virus coded polypeptide, the non-structural protein (NS), is made in only small amounts in the coupled system although it is a major virus coded product of infected cells early in infection. © 1979 Springer-Verlag.
