Schuhmacher, Beldar et al. design a super-substrate peptide based on the substrate sequence specificity of the SETD2 protein lysine methyltransferase. SETD2 methylates this super-substrate 290-fold more efficiently than the original H3K36 peptide. This study illustrates that substrate sequence design can improve the activity of protein lysine methyltransferases.
