DNA Methyltransferase
DNMTs; DNA MTases
DNA methyltransferases (DNMTs) are a family of “writer” enzymes responsible for DNA methylation that is the addition of a methyl group to the carbon atom number five (C5) of cytosine. Mammalians encode five DNMTs: DNMT1, DNMT2, DNMT3A-DNMT3B (de novo methyltransferases), and DNMTL. DNMT1, DNMT3A, and DNMT3B are the three active enzymes that maintain DNA methylation. DNMT3L has no catalytic activity and functions as a regulator of DNMT3A and DNMT3B, whereas DNMT2 acts as a tRNA transferase rather than a DNA methyltransferase.
DNA methylation is a vital modification process in the control of genetic information, which contributes to the epigenetics by regulating gene expression without changing the DNA sequence. In prokaryotes, DNA methylation is essential for transcription, the direction of post-replicative mismatch repair, the regulation of DNA replication, cell-cycle control, bacterial virulence, and differentiating self and non-self DNA. In mammalians, DNA methylation is crucial in many key physiological processes, including the inactivation of the X-chromosome, imprinting, and the silencing of germline-specific genes and repetitive elements.

Decitabine methanesulfonate
0 ImagesCat. No.: HY-A0004BCAS No.: 879492-57-6Synonyms: 5-Aza-2'-deoxycytidine methanesulfonate; 5-AZA-CdR methanesulfonate; NSC 127716 methanesulfonateDecitabine methanesulfonate (5-Aza-2'-deoxycytidine methanesulfonate) is an orally active Deoxycytidine analogue antimetabolite and DNA methyltransferase inhibitor. Decitabine methanesulfonate incorporates into DNA in place of cytosine can covalently trap DNA methyltransferase to DNA causing irreversible inhibition of the enzyme. Decitabine methanesulfonate induces cell G2/M arrest and cell Apoptosis. Decitabine has potent anticancer activity.

5-Aza-dCTP
0 ImagesCat. No.: HY-185899CAS No.: 72052-96-1Synonyms: 5-Aza-2'-deoxycytidine-5′-triphosphate5-Aza-dCTP (5-Aza-2'-deoxycytidine-5′-triphosphate) is a nucleotide analog that acts as a substrate for mammalian DNA polymerase α (Km = 3.0 μM) and a weak competitive inhibitor of this enzyme (Ki = 4.3 μM). 5-Aza-dCTP inhibits DNA polymerase α via incorporation into DNA through Watson-Crick base pairing, inhibits DNA methyltransferases via incorporation into hemimethylated DNA, and induces mutations in HIV-1 via incorporation into viral DNA during synthesis. 5-Aza-dCTP reverses the inhibitory effect of dTTP on dCMP deaminase, and allosterically activates dCMP deamination to the same extent as dCTP. 5-Aza-dCTP is applicable to research related to leukemia and type 1 human immunodeficiency virus infection.
