'''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.  CxxC domain is a zinc finger domain.
