Cytosine methyltransferase
WebThe various classes of methyltransferase may show differential activity on cytosines in different sequence contexts. Chromomethylases may preferentially methylate cytosines in CpNpG sequences while the Arabidopsis METI methyltransferase shows a preference for cytosines in CpG sequences. WebThiopurine S-methyltransferase (TPMT) is a cytosolic enzyme that inactivates thiopurine drugs such as 6-mercaptopurine and azathioprine through methylation. There is substantial variability in TPMT enzyme activity between individuals, and it has been found that this variability can be attributed to polymorphisms in the TPMT gene.

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 ... DNA (cytosine-5)-methyltransferase 3A is an enzyme that catalyzes the transfer of methyl groups to specific CpG structures in DNA, a process called DNA methylation. The enzyme is encoded in humans by the DNMT3A gene. This enzyme is responsible for de novo DNA methylation. Such function is to be distinguished from maintenance DNA methylation which ensures the fidelity o…
