Methyltransferase - an overview | ScienceDirect Topics
WebThe methyltransferases are an eclectic mix of enzymes of which the majority, over 95%, uses S -adenosyl- l -methionine (Ado-Met) as the methyl donor. The basic methyl transfer reaction is the catalytic attack of a nucleophile (carbon, oxygen, nitrogen, or sulfur) on a methyl group to form methylated derivatives of proteins, lipids ...
DNA methyltransferase - Wikipedia
WebIn 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.
