In enzymology, an acetoin-ribose-5-phosphate transaldolase () is an enzyme that catalyzes the chemical reaction :3-hydroxybutan-2-one + D-ribose 5-phosphate acetaldehyde + 1-deoxy-D-altro-heptulose 7-phosphate Thus, the two substrates of this enzyme are 3-hydroxybutan-2-one and D-ribose 5-phosphate, whereas its two products are acetaldehyde and 1-deoxy-D-altro-heptulose 7-phosphate. This enzyme belongs to the family of transferases, specifically those transferring aldehyde or ketonic groups (transaldolases and transketolases, respectively). The systematic name of this enzyme class is 3-hydroxybutan-2-one:D-ribose-5-phosphate aldehydetransferase. Other names in common use include 1-deoxy-D-altro-heptulose-7-phosphate synthetase, 1-deoxy-D-altro-heptulose-7-phosphate synthase, 3-hydroxybutan-2-one:D-ribose-5-phosphate aldehydetransferase (and substrate name ). It employs one cofactor, thiamin diphosphate. ==References== * 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「Acetoin—ribose-5-phosphate transaldolase」の詳細全文を読む スポンサード リンク
