Assembly of hepatitis delta virus-like empty particles in yeast.
Large delta antigen (L-HDAg) of hepatitis delta virus (HDV) and small-form hepatitis B surface antigen (HBsAg) of helper hepatitis B virus have previously been shown to be the minimum components for the assembly of HDV-like particles in mammalian cells. Extending from this finding, we coexpressed L-HDAg and small HBsAg in Saccharomyces cerevisiae to study their assembly in yeast cells. The asse...
متن کاملEnvelope proteins derived from naturally integrated hepatitis B virus DNA support assembly and release of infectious hepatitis delta virus particles.
UNLABELLED A natural subviral agent of human hepatitis B virus (HBV), hepatitis delta virus (HDV), requires only the envelope proteins from HBV in order to maintain persistent infection. HBV surface antigens (HBsAgs) can be produced either by HBV replication or from integrated HBV DNA regardless of replication. The functional properties of the integrant-generated HBsAgs were examined using two ...
متن کاملHepatitis B virus capsid assembly Assembly pathway of hepatitis B core virus-like particles from genetically fused dimers
Background: We studied assembly of HBV capsids using a genetically-fused dimer. Results: Assembly intermediates composed of two, three and five copies of a fused dimer have been isolated. Conclusion: Capsid assembly could progress using dimeric, trimeric and pentameric intermediates. Significance: The low abundance and transient nature of assembly intermediates make analysis challenging, howeve...
متن کاملHepatitis Delta Virus RNA Replication
Hepatitis delta virus (HDV) is a distant relative of plant viroids in the animal world. Similar to plant viroids, HDV replicates its circular RNA genome using a double rolling-circle mechanism. Nevertheless, the production of hepatitis delta antigen (HDAg), which is indispensible for HDV replication, is a unique feature distinct from plant viroids, which do not encode any protein. Here the HDV ...
متن کاملHepatitis Delta Virus: A Peculiar Virus
The hepatitis delta virus (HDV) is distributed worldwide and related to the most severe form of viral hepatitis. HDV is a satellite RNA virus dependent on hepatitis B surface antigens to assemble its envelope and thus form new virions and propagate infection. HDV has a small 1.7 Kb genome making it the smallest known human virus. This deceivingly simple virus has unique biological features and ...
