Abstract: The present invention relates to a chimeric enzyme comprising or consisting of at least one catalytic domain of a capping enzyme and at least one RNA-binding domain of a protein-RNA tethering system as well as its application for the production of an RNA molecule with a 5?-terminal cap.

Abstract: The present invention concerns a method for expressing a recombinant DNA molecule in a eukaryotic host cell, comprising the steps of: (a) expressing or introducing at least one chimeric protein, in said host cell, wherein said chimeric protein comprises: (i) at least one catalytic domain of a capping enzyme, in particular selected in the group consisting of cap-0 canonical capping enzymes, cap-0 non-canonical capping enzymes, cap-1 capping enzymes and cap-2 capping enzymes; and (ii) at least one catalytic domain of a DNA-dependent RNA polymerase, in particular a bacteriophage DNA-dependent RNA polymerase, (b) constitutively or transiently downregulating the phosphorylation level of subunit a of translation initiation factor eIF2 (eIF2?) in said host cell.

Abstract: The invention provides a chimeric enzyme comprising at least one catalytic domain of a RNA triphosphatase, at least one catalytic domain of a guanylyltransferase, at least one catalytic domain of a N7-guanine methyltransferase, and at least one catalytic domain of a DNA-dependant RNA polymerase. The invention also provides pharmaceutical composition comprising said chimeric enzyme and uses of said chimeric enzyme.
