In enzymology, an adenosylhomocysteine nucleosidase () is an enzyme that catalyzes the chemical reaction :S-adenosyl-L-homocysteine + H2O S-(5-deoxy-D-ribos-5-yl)-L-homocysteine + adenine Thus, the two substrates of this enzyme are S-adenosyl-L-homocysteine and H2O, whereas its two products are S-(5-deoxy-D-ribos-5-yl)-L-homocysteine and adenine. This enzyme belongs to the family of hydrolases, specifically those glycosylases that hydrolyse N-glycosyl compounds. The systematic name of this enzyme class is S-adenosyl-L-homocysteine homocysteinylribohydrolase. Other names in common use include S-adenosylhomocysteine hydrolase (ambiguous), S-adenosylhomocysteine nucleosidase, 5'-methyladenosine nucleosidase, S-adenosylhomocysteine/5'-methylthioadenosine nucleosidase, and AdoHcy/MTA nucleosidase. This enzyme participates in methionine metabolism. ==Structural studies== As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , , and . 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「Adenosylhomocysteine nucleosidase」の詳細全文を読む スポンサード リンク
