Abstract
(EN)
The present invention relates to a recombinant severe acute respiratory syndrome coronavirus (SARS-CoV) non-structural protein (nsp) 12 with an RNA polymerase activity, its expression vector, its preparation method, and its use. According to the present invention, a soluble recombinant SARS-CoV nsp 12 with an RdRp activity of initiating SARS-CoV genome synthesis can be over-expressed in the transformed host cells, and conveniently purified with high purity. An in vitro replication system important for studying SARS-CoV replication can be established with the purified recombinant SARS-CoV nspl2. SARS-CoV nspl2 produced by the present invention can also be used as a target for the development of anti-viral agents against SARS-CoV. In addition, materials inhibiting RNA-dependent RNA polymerase (RdRp) activity of nsp 12 can be screened efficiently according to the present invention as the optimal conditions for the RdRp assay with SARS-CoV nsp 12 were found.

La présente invention concerne une protéine non structurelle (nsp) 12 recombinante du coronavirus du syndrome de détresse respiratoire aiguë sévère (SARS-CoV) avec une activité ARN polymérase, son vecteur d’expression, son procédé de préparation et son utilisation. Selon la présente invention, une nsp 12 recombinante soluble du SARS-CoV, avec une activité RdRp d’initiation de la synthèse du génome du SARS-CoV, peut être surexprimée dans les cellules hôtes transformées, et purifiée de manière appropriée avec une pureté élevée. Un système de réplication in vitro, important pour l’étude de la réplication du SARS-CoV, peut être mis en place avec la nsp12 recombinante purifiée du SARS-CoV. La nsp 12 du SARS-CoV produite par la présente invention peut aussi être utilisée en tant que cible pour le développement d’agents antiviraux contre le SARS-CoV. En outre, la présente invention permet de cribler efficacement des matériaux inhibant l’activité ARN polymérase ARN-dépendante (RdRp) de la nsp 12, puisque les conditions optimales pour le dosage de la RdRp avec la nsp 12 du SARS-CoV ont été découvertes.
