Genotype-specific differences in structural features of hepatitis C virus (HCV) p7 membrane protein.

ABSTRACT: The 63 amino acid polytopic membrane protein, p7, encoded by hepatitis C virus (HCV) is involved in the modulation of electrochemical gradients across membranes within infected cells. Structural information relating to p7 from multiple genotypes has been generated in silico (e.g. genotype (GT) 1a), as well as obtained from experiments in form of monomeric and hexameric structures (GTs 1b and 5a, respectively). However, sequence diversity and structural differences mean that comparison of their channel gating behaviour has not thus far been simulated. Here, a molecular model of the monomeric GT 1a protein is optimized and assembled into a hexameric bundle for comparison with both the 5a hexamer structure and another hexameric bundle generated using the GT 1b monomer structure. All bundles t
