Hepatitis A virus (HAV) infects African green monkey kidney (AGMK) cells via the HAV cellular receptor-1 (havcr-1), a mucin-like type 1 integral-membrane glycoprotein of unknown natural function. The ectodomain of havcr-1 contains an N-terminal immunoglobulin-like cysteine-rich region (D1), which
The preferred amino acid residues at the P'1 and P'2 positions of peptide substrates of the 3C proteinase from hepatitis A virus (HAV-3C) have been determined by a rapid screening method. The enzyme was presented with two separate mixtures of N-terminal acetylated peptides, which were identical in
Nonstructural protein 5A (NS5A) of hepatitis C virus (HCV) is an indispensable component of the HCV replication and assembly machineries. Although its precise mechanism of action is not yet clear, current evidence indicates that its structure and function are regulated by the cellular peptidylprolyl
