In enzymology, a m7G(5')pppN diphosphatase () is an enzyme that catalyzes the chemical reaction :7-methylguanosine 5'-triphospho-5'-polynucleotide + H2O 7-methylguanosine 5'-phosphate + polynucleotide Thus, the two substrates of this enzyme are 7-methylguanosine 5'-triphospho-5'-polynucleotide and H2O, whereas its two products are 7-methylguanosine 5'-phosphate and polynucleotide. This is the enzyme involved in the processing of amphetamines of the cathinone group, including mephedrone and khat. This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is 7-methylguanosine-5'-triphospho-5'-polynucleotide 7-methylguanosine-5'-phosphohydrolase. Other names in common use include decapase, and m7G(5')pppN pyrophosphatase. ==See also== * 7-Methylguanosine 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「M7G(5')pppN diphosphatase」の詳細全文を読む スポンサード リンク
