产品名称:
O6-methylguanine-DNA Methyltransferase (human, recombinant)
别名:
MGMT
产品描述:
O6-methylguanine-DNA Methyltransferase (MGMT) is a DNA repair enzyme responsible for demethylating O6-methylguanine (O6-mG).{20209} The methylation of guanine at O6 to form O6-mG allows base-pairing to thymine rather than cytosine during DNA replication. MGMT prevents mutations by transferring the methyl group from O6-mG to MGMT cysteine 145, restoring guanine. This transfer results in a covalent bond between MGMT cysteine 145 and the methyl group, and so MGMT is a single-turnover, "suicide" enzyme. The assay used to test MGMT is the demethylation of a synthesized, double-stranded, DNA oligonucleotide.{20210} Demethylation removes an O6-methyl group to expose a restriction site for the restriction endonuclease PvuII. Lanes A-E show 200 ng of methylated dsDNA treated with increasing amounts of MGMT prior to PvuII digestion.
