Identification of two new polypeptides encoded by mRNA5 of the coronavirus infectious bronchitis virus 1992-01-31 .txt text/plain 3164 137 50 We report here that two polypeptides with the sizes expected for the 5a and 5b products can be synthesised by in vitro translation of a single artificial mRNA containing both the 5a and 5b ORFs. To establish whether these polypeptides represent genuine virus gene products, both the 5a and 5b coding sequences were expressed as bacterial fusion proteins, and these were used to raise monospecific antisera.
