'''Histone methyltransferase''' (HMT) are histone-lysine N-methyltransferase (KHMT) and histone-arginine N-methyltransferase (RHMT) which catalyzes the transfer of methyl groups to lysine and arginine residues of histones. HMT use S-adenosyl methionine (SAM) or S-adenosyl homocysteine (SAH) as the methyl donor. KHMT can be SET domain-containing or non-SET domain-containing. The SET domain contains the catalytic core of KHMT and targets the lysine tail region of KHMT.
