AbstractSite-selective lysine post-translational modifications such as acetylation, methylation, hydroxylation, and isopeptide formation mediate the precise control of important signaling events in cells with unmistakable accuracy. This unparalleled site selectivity (modification of a single lysine in a particular protein in the proteome) is still a challenge for non-enzymatic protein reactions; the difficulty lies in the differentiation of the lysine ε-amino group from other reactive groups and in the precise pinpointing of one particular lysine ε-amino group out of many other lysine ε-amino groups and the N-terminal amine of the protein that have similar chemical reactivity. Here, we have explored proximal lysine conjugation reactions through peptide-guided fluorodinitrobenzene, isothiocyanate, and phenyl ester reactions and have validated the site-specific targeting of the ε-amino group of one single lysine in natural proteins that contain multiple lysine residues. This precise site selectivity is a result of the proximity-induced reactivity guided by a specific protein–peptide interaction: the binding interaction preorganizes an amine-reactive group in the peptide and one of the lysine side chain ε-amino groups of the protein into close proximity, thereby confining the reactivity to a selected area of the target protein. The binding-guide lysine reactions were first examined on an SH3 domain and then tested on several ubiquitin-like proteins such as SUMO, Atg8 protein family, plant ATG8, and mammalian LC3 proteins that contain at least seven lysine residues on the surface. Exquisite site selectivity was confirmed in all of the proteins tested. A set of amine reactions were tested for their feasibility in the site-selective lysine reaction. Selected amine-reactive groups were optimized, and the reaction sites on the LC3 protein were confirmed by mass spectrometry.
