Enzyme responsible for methylating dna
WebDNA demethylation can be produced by at least three enzyme families: (i) the ten-eleven translocation (TET) family, mediating the conversion of 5mC into 5hmC; (ii) the … WebDNA methylation is an epigenetic mechanism that occurs by the addition of a methyl (CH 3) group to DNA, thereby often modifying the function of the genes and affecting gene expression. The most widely characterized …

Question: What is the enzyme responsible for methylating DNA? How does a drug … In biochemistry, the DNA methyltransferase (DNA MTase, DNMT) family of enzymes catalyze the transfer of a methyl group to DNA. DNA methylation serves a wide variety of biological functions. All the known DNA methyltransferases use S-adenosyl methionine (SAM) as the methyl donor. See more Substrate MTases can be divided into three different groups on the basis of the chemical reactions they catalyze: • m6A - those that generate N6-methyladenine See more DNMT inhibitors Because of the epigenetic effects of the DNMT family, some DNMT inhibitors are under investigation for treatment of some cancers: • Vidaza (azacitidine) in phase III trials for myelodysplastic syndromes See more • Smith SS (1994).
