In enzymology, a mRNA (guanine-N7-)-methyltransferase also known as mRNA cap guanine-N7 methyltransferase is an enzyme that catalyzes the chemical reaction :S-adenosyl-L-methionine + G(5')pppR-RNA S-adenosyl-L-homocysteine + m7G(5')pppR-RNA (mRNA containing an N7-methylguanine cap) Thus, the two substrates of this enzyme are S-adenosyl methionine and G(5')pppR-RNA, whereas its two products are S-adenosylhomocysteine and m7G(5')pppR-RNA. This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. In humans, mRNA cap guanine-N7 methyltransferase is encoded by the ''RNMT'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=8731 )〕 == Nomenclature == The systematic name of this enzyme class is S-adenosyl-L-methionine:mRNA (guanine-N7-)-methyltransferase. Other names in common use include: * messenger ribonucleate guanine 7-methyltransferase, * guanine-7-methyltransferase, * messenger RNA guanine 7-methyltransferase, and * S-adenosyl-L-methionine:mRNA (guanine-7-N-)-methyltransferase. 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「MRNA (guanine-N7-)-methyltransferase」の詳細全文を読む スポンサード リンク
