WebCytosine methylation does not reinforce or replace ancestral gene regulation pathways but instead endows methylated genomes with the ability to repress specific promoters in a manner that is buffered against changes in the internal and external environment. In mammalian cells, cytosine-specific methyltransferases methylate certain CpG sequences, which are believed to modulate gene expression and cell differentiation. In bacteria , these enzymes are a component of restriction-modification systems and serve as valuable tools for the … See more 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 … See more At least four differently active DNA methyltransferases have been identified in mammals.

WebOct 1, 2007 · Cytosine-5 DNA methyltransferases (C5-MTases) accomplish two functions: recognition of a specific DNA sequence and catalysis of the transfer of a methyl group from the cofactor S-adenosyl-l-methionine (AdoMet) to carbon 5 in the pyrimidine ring of cytosine residues [7], [8]. These functions are separated into two domains: the variable N ...
