- Using an evolved pyrrolysyl-tRNA synthetase-tRNAᴾʸˡ pair, a Se-alkylselenocysteine was genetically incorporated into histone H3 with a high protein expression yield. Quantitative oxidative elimination of Se-alkylselenocysteine followed by Michael addition reactions with various thiol nucleophiles generated biologically active mimics of H3 with posttranslational modifications including lysine methylation, lysine acetylation, and serine phosphorylation.
