Two mechanisms exist for the incorporation of B5 into extracellular virions, one of which is dependent on A33. In the companion to this paper (W. M. Chan and B. M. Ward, J. Virol. 86:8210-8220, 2012), we show that the lumenal domain of A33 is sufficient for interaction with the coiled-coil domain of B5 and capable of directing B5-green fluorescent protein (GFP) into extracellular virions. Here, we have created a panel of charge-to-alanine mutations in the lumenal domain of A33 to map the B5 interaction site. While none of these mutations abolished the interaction with B5, a subset displayed an increased interaction with both B5 and B5-GFP. Both B5 and B5-GFP recombinant viruses expressing these mutant proteins in place of normal A33 had a small-plaque phenotype. The increased interaction of the mutant proteins was detected during infection, suggesting that normally the interaction is either weak or transient. In addition, the increased A33-B5 interaction was detected on virions produced by recombinant viruses and correlated with reduced target cell binding. Taken together, these results show that both B5 and B5-GFP interact with A33 during infection and that the duration of this interaction needs to be regulated for the production of fully infectious extracellular virions.

Increased Interaction between Vaccinia Virus Proteins A33 and B5 Is Detrimental to Infectious Extracellular Enveloped Virion Production
