Abstract excerpt
Histone methylation is an epigenetic mark essential for gene regulation and development. We introduce peptide SPOT synthesis to study sequence specificity of the Dim-5 histone-3 lysine-9 methyltransferase. Dim-5 recognizes R8-G12 of the H3 tail with T11 and G12 being the most important specificity determinants. Exchange of H3 tail residue S10 and T11 by E strongly reduced methylation by Dim-5, suggesting that...
