Hepatitis G virus (HGV) nonstructural protein 3 (NS3) contains amino acid sequence motifs typical of ATPase and RNA helicase proteins. In order to examine the RNA helicase activity of the HGV NS3 protein, the NS3 region (amino acids 904 to 1580) was fused with maltose-binding protein (MBP), and the
OBJECTIVE
To develop a novel treatment method for hepatitis B virus (HBV) infection, we aimed to make a human monoclonal antibody inhibiting reverse transcriptase (RT) activity of P protein which was important in HBV replication by using phage display technique. Therefore, we analysed the usability
The genomic region encoding the core (C) protein (amino acids 1-162) of hepatitis C virus (HCV) was expressed in Escherichia coli as a recombinant (re-) protein with the maltose-binding protein (MBP) using the prokaryotic expression vector pMAL-CR1. The fusion protein (C::MBP) was identified as a
Hepatitis C virus (HCV) non-structural protein 5B (NS5B) is an RNA replicase. We expressed full-length NS5B (591 amino acid residues) in Escherichia coli as a fusion protein with maltose binding protein (MBP-NS5B). MBP-NS5B was recovered in the soluble fraction after centrifugation at 40,000 x g and
PreS1 region gene fragment encoding the N-terminal 56 amino acid (aa) of hepatitis B virus (HBV, adr subtype), which encodes B- and T-cell epitopes and an hepatocyte receptor binding site, was synthesized by PCR and fused to the 3'-end of MalE gene encoding maltose-binding protein (MBP) to yield
The hepadnavirus P gene product is a multifunctional protein with priming, DNA- and RNA-dependent DNA polymerase, and RNase H activities. Nested N- or C-terminal deletion mutations and deletions of domain(s) in human HBV polymerase have been made. Wild-type and deletion forms of MBP-fused HBV
We present a simple and flexible procedure to elicit and assay anti-peptide antibodies without peptide synthesis. It consists of expressing the peptide of interest in the form of a genetic insert within two different "recipient" bacterial proteins. One hybrid protein is used as immunogen for the
The HBx (hepatitis B virus X protein) is a multifunctional regulator of cellular signal transduction and transcription pathways in host-infected cells. Evidence suggests that HBx has a critical role in the pathogenesis of hepatocellular carcinoma. However, the lack of efficient large-scale
