3.5.1.114 additional information the enzyme directly binds to the hepatitis C virus core protein and also reveals a weak endopeptidase activity towards the N-terminus of hepatitis C virus core protein, interaction analysis of the enzyme with N-terminal peptides derived from hepatitis C virus core protein via surface plasmon resonance method, overview 3.5.1.114 N-acetyl-S-geranylgeranyl-L-cysteine + H2O the 90000-100000 Da AA3 form (that is detected in most hepatocellular carcinoma cell lines but not in normal hepatocytes) is functionally active and together with the normal 35000 Da AA3 form mediates the deacetylation of N-acetylfarnesylcysteine and N-acetylgeranylgeranylcysteine 3.5.1.114 N-acetyl-S-[(2E,6E)-farnesyl]-L-cysteine + H2O the 90000-100000 Da AA3 form (that is detected in most hepatocellular carcinoma cell lines but not in normal hepatocytes) is functionally active and together with the normal 35000 Da AA3 form mediates the deacetylation of N-acetylfarnesylcysteine and N-acetylgeranylgeranylcysteine 3.5.1.114 Nalpha-acetylated peptide + H2O N-terminal peptides derived from hepatitis C virus core protein
