Bioorthogonal ligation methods with improved reaction rates and less obtrusive components are needed for site-specifically labeling proteins without catalysts. Currently no general method exists for in vivo site-specific labeling of proteins that combines fast reaction rate with stable, nontoxic and chemoselective reagents. To overcome these limitations we have developed a tetrazine-containing amino acid, 1, that is stable inside living cells. We have site-specifically genetically encoded this unique amino acid in response to an amber codon allowing a single 1 to be placed at any location in a protein. We have demonstrated that protein containing 1 can be ligated to a conformationally strained trans-cyclooctene, 2, in vitro and in vivo with reaction rates significantly faster than most commonly used labeling methods.
