Grass carp reovirus (GCRV) is a member of the genus Aquareovirus in the family Reoviridae, and contains five core proteins (VP1-VP4 and VP6) and two outer-capsid proteins (VP5 and VP7) in its particle. Previous studies have revealed that the outer-capsid proteins of reovirus are responsible for initiating infection, but the mechanism is poorly understood. Using baculovirus-expressed VP5 and VP7 to recoat purified cores, in vitro assembly of GCRV was achieved in this study. Recoated GCRV (R-GCRV) closely resembled native GCRV (N-GCRV) in particle morphology, protein composition and infectivity. Similar to N-GCRV, the infectivity of R-GCRV could be inhibited by treating cells with the weak base NH4Cl. In addition, recoated particles carrying an Asn -> Ala substitution at residue 42 of VP5 (VP5(N42A)/VP7 R-GCRV) were no longer infectious. These results provide strong evidence that autocleavage of VP5 is critical for aquareovirus to initiate efficient infection.
