These tails are subject to several post-translational covalent modifications, together with acetylation, phosphorylation, ubiquitination, sumoylation and methylation (reviewed in 1 ). Methylation been found on a variety of lysine residues in varied histones: K4 (utilizing the one-letter amino-acid code for lysine), K9, K27, K36 and K79 in histone H3, K20 in histone H4, K59 in the globular area of histone H4 2 and K26 of histone H1B three Several proteins chargeable for the methylation of particular residues have been characterised, and all however one of these comprises a SET area
