A synthetic peptidecontaining two Nε-methyl lysines (Ac-K(Nε-Me)GYTGYTGK(Nε-Me)D-OH) was alkylated with bipyridine (bipy) ligands substituted at the fifth (MP-5) and sixth (MP-6) positions, thereby creating Ac-K(Nε-Me, Nε-Bipy)GYTGYTGK(Nε-Me, Nε-Bipy)D-OH. Peptides with a bipyridine at the 6-position did not bind to Fe2+ and Zn2+. Peptides with a bipyridine at the 5-position bound these metals, and

targets to distinguish selectively in water using synthetic receptors. To date, trimethyllysine (Kme3) is the only post translational modification (PTM) of the eight possible methylation states of Lys and Arg that can be recognized selectively. Here, we report the first synthetic receptor capable of selectively recognizing asymmetricdimethylarginine (Rme2a). This was achieved by using a biased dynamic

Histone lysine methylation is regulated by Nε-methyltransferases, demethylases, and Nε-methyl lysine binding proteins. Thermodynamic, catalytic and computational studies were carried out to investigate the interaction of three epigenetic protein classes with synthetic histone substrates containing L- and D-lysine residues. The results reveal that out of the three classes, Nε-methyl lysine binding proteins
