INCORPORATION OF METHYL LYSINE INTO POLYPEPTIDES

摘要

The invention relates to A method of making a polypeptide comprising at least one Nε-methyl-lysine at a specific site in said polypeptide, said method comprising (a) genetically directing the incorporation of R—Nε-methyl-lysine into said polypeptide, wherein R comprises an auxiliary group; and (b) catalysing the removal of R from the polypeptide of (a). In particular the invention relates to such a method wherein genetically directing the incorporation of R—Nε-methyl-lysine into said polypeptide comprises arranging for the translation of a RNA encoding said polypeptide, wherein said RNA comprises an amber codon, and wherein said translation is carried out in the presence of an amber tRNA charged with R—Nε-methyl-lysine.
