Overexpression of recombinant proteins with a C‐terminal thiocarboxylate: Implications for protein semisynthesis and thiamin biosynthesis Academic Article uri icon


  • A facile and rapid method for the production of protein C-terminal thiocarboxylates on DNA-encoded polypeptides is described. This method, which relies on the mechanism of the cleavage reaction of intein-containing fusion proteins, can produce multi-milligram quantities of protein C-terminal thiocarboxylate quickly and inexpensively. The utility of this method for protein semisynthesis and implications for studies on the biosynthesis of thiamin are discussed.
