In enzymology, a trans-octaprenyltranstransferase () is an enzyme that catalyzes the chemical reaction :all-trans-octaprenyl diphosphate + isopentenyl diphosphate diphosphate + all-trans-nonaprenyl diphosphate Thus, the 2 substrates of this enzyme are all-trans-octaprenyl diphosphate and isopentenyl diphosphate, whereas its two products are diphosphate and all-trans-nonaprenyl diphosphate. This enzyme belongs to the family of transferases, specifically those transferring aryl or alkyl groups other than methyl groups. The systematic name of this enzyme class is (E)-octaprenyl-diphosphate:isopentenyl-diphosphate octaprenyltranstransferase. Other names in common use include all-trans-nonaprenyl-diphosphate synthase, solanesyl-diphosphate synthase, solanesyl pyrophosphate synthetase, SPP synthase, nonaprenyl pyrophosphate synthetase, polyprenylpyrophosphate synthetase, terpenoidallyltransferase, terpenyl pyrophosphate synthetase, trans-octaprenyltranstransferase, and trans-prenyltransferase. This enzyme participates in biosynthesis of steroids. ==Structural studies== As of late 2007, 16 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「Trans-octaprenyltranstransferase」の詳細全文を読む スポンサード リンク
