3.5Å cryoEM Structure of Hepatitis B Virus Core Assembled from Full-Length Core Protein

The capsid shell of infectious hepatitis B virus (HBV) is composed of 240 copies of a single protein called HBV core antigen (HBc). An atomic model of a core assembled from truncated HBc was determined previously by X-ray crystallography. In an attempt to obtain atomic structural information of HBV core in a near native, non-crystalline environment, we reconstructed a 3.5Å-resolution structure ...

Overexpression of Full-Length Core Protein of Hepatitis C Virus by Escherichia coli Cultivated in Stirred Tank Fermentor

The mature core protein of the Hepatitis C virus (HCVC173) carrying pelB as a signal peptide (PelB::core) was overexpressed in Escherichia coli as 18% and 23.3% of the host’s total protein, in flask and fermentor cultivation, respectively. A final specific yield of 25 ± 1 mg HCVC173/g dry cell weight and an overallproductivity of 51±1 mg HCVC173/l/h were obtained in the stirred-tank ferme...

Mutations in pre-core and basal-core promoter regions of hepatitis B virus in chronic HBV patients from Golestan, Iran

Objective(s): It has been reported that the mutation of the pre-core (PC) and basal-core promoter (BCP) may play an important role in the development of HBV-related hepatocellular carcinoma (HCC). In this study the PC and BCP mutations were investigated in chronic HBV patients. Materials and Methods:In this study, 120 chronic HBV patients from Golestan, Northeast of Iran who were not vaccinated...

Hepatitis B virus capsid particles are assembled from core-protein dimer precursors.

Our studies on the assembly of hepatitis B virus capsids or core particles in Xenopus oocytes have demonstrated that unassembled p21.5 core proteins ("free p21.5") provide a pool of low-molecular-mass precursors for core-particle assembly. Here we have characterized this material. Free p21.5 sedimented through gradients of 3-25% sucrose (wt/vol) as a single protein species of approximately 40 k...

Significance of Hepatitis B Core Antibody as the Only Marker of Hepatitis B Virus Infection in High Risk Patients

  Background and Objective: Presence of hepatitis B core antibody (anti-HBc) in the absence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) is defined, as isolated anti-HBc. little is known about the clinical significance of the isolated anti-HBc in hepatitis B virus (HBV) infections. The aim of this study was to assess the significance of anti-HBc as the onl...
