Genetically encoding Nε-acetyllysine in recombinant proteins

Abstract

Nε-acetylation of lysine (1) is a reversible post-translational modification with a regulatory role that rivals that of phosphorylation in eukaryotes. No general methods exist to synthesize proteins containing Nε-acetyllysine (2) at defined sites. Here we demonstrate the site-specific incorporation of Nε-acetyllysine in recombinant proteins produced in Escherichia coli via the evolution of an orthogonal Nε-acetyllysyl-tRNA synthetase/tRNACUA pair. This strategy should find wide applications in defining the cellular role of this modification.
