DNA methylation serves a wide variety of biological functions. All the known DNA methyltransferases use S-adenosyl methionine (SAM) as the methyl donor.en.wikipedia.org/wiki/DNA_methyltransferaseThe DNA methyltransferase family of enzymes consists of five members, namely, DNA methyltransferase1, DNA methyltransferase2, DNA methyltransferase3a, DNA methyltransferase3b, and DNA methyltransferase3L.www.sciencedirect.com/topics/biochemistry-geneti…Members of the DNA methyltransferase (DNMT) family have been recognized as major epigenetic regulators of altered gene expression during tumor development. They establish and maintain DNA methylation of the CpG island of promoter and non-CpG region of the genome.www.mdpi.com/1718-7729/32/2/88The DNMTs family is the DNA methylator in living beings. DNMTs have two domains: catalytic domain in the carboxy-terminal extreme, with the conserved catalytic motives, and location domain in the amino-terminal extreme, with the location and interaction chromatin motives.www.mdpi.com/1422-0067/23/16/8994In eukaryotes, these enzymes are grouped into one family consisting of five members: Dnmt1, Dnmt2, Dnmt3a, Dnmt3b and Dnmt3L [1, 2]. Dnmt1 is responsible for the maintenance of DNA methylation after each round of replication [3, 4].bmcmolbiol.biomedcentral.com/articles/10.1186/14…
