This invention discloses a recombinant 2-O-sulfonyltransferase mutant and its preparation method, belonging to the field of biotechnology. The recombinant enzyme sequence is formed by fusing a truncated (E28~N356) mutant of hamster-derived 2-O-sulfonyltransferase (L119V-R188E-A240I) with an N-terminal maltose-binding protein (MBP) tag. The recombinant 2-O-sulfonyltransferase mutant exhibits higher activity, 1.9 times that of the recombinant wild type, and greater stability, retaining 86.6% of its activity after 5 days at room temperature. Furthermore, the soluble expression level of this recombinant mutant 2-O-sulfonyltransferase is increased by 5 times. This mutant, as a novel biocatalyst with high efficiency, stability, and controllable production costs, has significant application value and broad industrialization prospects in the industrial enzymatic synthesis of glycosaminoglycans such as heparin and heparan sulfate.

A solution has been discovered that provides a more effective Coronavirus vaccine. The solution is an mRNA vaccine encoding a SARS-CoV-2 nucleoprotein (N) (mRNA-N) in combination with an mRNA vaccine encoding SARS-CoV-2 spike protein(S) (mRNA-S). Chemically modified mRNA-N (pseudouridine) and / or chemically modified mRNA-S (pseudouridine) can be synthesized and packaged in lipid nanoparticles (LNP). In mouse and hamster models, it was shown that mRNA-N alone is immunogenic and can significantly diminish viral loads in the mouse lung after prime-boost intramuscular immunization. In addition, the combinatorial mRNA-N / mRNA-S vaccination induces substantially stronger protection against SARS-CoV-2 than vaccination with mRNA-S alone.
