Identification of Aptamer-Binding Sites in Hepatitis C Virus Envelope Glycoprotein E2
Hepatitis C Virus (HCV) encodes two envelope glycoproteins, E1 and E2. Our previous work selected a specific aptamer ZE2, which could bind to E2 with high affinity, with a great potential for developing new molecular probes as an early diagnostic reagents or therapeutic drugs targeting HCV. In this study, the binding sites between E2 and aptamer ZE2 were further explored. E2 was truncated to 15...
متن کاملOverexpression 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...
متن کاملEvidence for a Complex Mosaic Genome Pattern in a Full-length Hepatitis C Virus Sequence
The genome of the hepatitis C virus (HCV) exhibits a high genetic variability. This remarkable heterogeneity is mainly attributed to the gradual accumulation of mutational changes, whereas the contribution of recombination events to the evolution of HCV remains controversial so far. While performing phylogenetic analyses including a large number of sequences deposited in the GenBank, we encount...
متن کاملLongitudinal Sequence and Functional Evolution within Glycoprotein E2 in Hepatitis C Virus Genotype 3a Infection
The E2 glycoprotein of Hepatitis C virus (HCV) is a major target of the neutralizing antibody (NAb) response with the majority of epitopes located within its receptor binding domain (RBD; 384-661). Within E2 are three variable regions located at the N-terminus (HVR1; 384-411), and internally at 460-480 (HVR2) and 570-580 [intergenotypic variable region (igVR)], all of which lie outside a conser...
متن کاملProduction and characterization of the ectodomain of E2 envelope glycoprotein of hepatitis C virus folded in the presence of full-length E1 glycoprotein.
Hepatitis C virus (HCV) envelope glycoproteins, E1 and E2, are involved in the first steps of virus infection. The E2 ectodomain can be produced as an isolated form (E2661). However, there is some concern about its proper conformation and the role that E1 can play as a chaperone for the folding of E2. In order to verify this fact we have expressed a chimeric protein (E1tmbE2) based on the full-...
