Abstract
This is a method for reproducing in vitro the RNA-dependent RNA polymerase activity associated with hepatitis C virus. The method is characterized in that sequences contained in NS5B are used in the reaction mixture. The terminal nucleotidyl transferase activity, a further property of the NS5B protein, can also be reproduced using this method. The method takes advantage of the fact that the NS5B protein, either purified to apparent homogeneity or present in extracts of overproducing organisms, can catalyze the addition of ribonucleotides to the 3′-termini of exogenous or endogenous RNA molecules. The invention also relates to a composition of matter that comprises sequences contained in NS5B, and to the use of these compositions for the set up of an enzymatic test capable of selecting, for therapeutic purposes, compounds that inhibit the enzymatic activity associated with NS5B.
