  通过定点诱变和形态发生研究三齿蒿法呢基二磷酸合酶和菊基二磷酸合酶的结构-功能

  摘要：

  来自 Artemisia tridentata ssp 的法呢基二磷酸合酶 (FPPase) 和菊基二磷酸合酶 (CPPase) 的氨基酸序列。Spiciformis，减去它们的叶绿体靶向区域，71% 相同，90% 相似。FPPase 通过将异戊烯基二磷酸 (IPP) 与二甲基烯丙基二磷酸 (DMAPP) 偶联，然后再与香叶基二磷酸 (GPP) 偶联，有效且选择性地合成“常规”倍半萜类法呢基二磷酸 (FPP)。相比之下，CPPase 是一种低效的混杂酶，它从两个分子的 DMAPP 中合成“不规则”单萜菊酯二磷酸 (CPP)、薰衣草二磷酸 (LPP) 和微量的马可二磷酸 (MPP)，并将 IPP 与 DMAPP 偶联以形成给 GPP。A. tridentata FPPase 和 CPPase 属于链延长蛋白家族 (PF00348)，萜类合酶超家族 (CL0613) 的一个亚群，其成员具有特征性

  The Biosynthetic Origin of Irregular Monoterpenes in Lavandula

  摘要：

  Lavender essential oils are constituted predominantly of regular monoterpenes, for example linalool, 1,8-cineole, and camphor. However, they also contain irregular monoterpenes including lavandulol and lavandulyl acetate. Although the majority of genes responsible for the production of regular monoterpenes in lavenders are now known, enzymes (including lavandulyl diphosphate synthase (LPPS)) catalyzing the biosynthesis of irregular monoterpenes in these plants have not been described. Here, we report the isolation and functional characterization of a novel cis-prenyl diphosphate synthase cDNA, termed Lavandula x intermedia lavandulyl diphosphate synthase (LiLPPS), through a homology-based cloning strategy. The LiLPPS ORF, encoding for a 305-amino acid long protein, was expressed in Escherichia coli, and the recombinant protein was purified by nickel-nitrilotriacetic acid affinity chromatography. The approximately 34.5-kDa bacterially produced protein specifically catalyzed the head-to-middle condensation of two dimethylallyl diphosphate units to LPP in vitro with apparent K-m and k(cat) values of 208 +/- 12 mu M and 0.1 s(-1), respectively. LiLPPS is a homodimeric enzyme with a sigmoidal saturation curve and Hill coefficient of 2.7, suggesting a positive co-operative interaction among its catalytic sites. LiLPPS could be used to modulate the production of lavandulol and its derivatives in plants through metabolic engineering.

  A side activity of a regular isoprenyl diphosphate synthase results in two non-head-to-tail terpene structures. For one of them, a cyclobutane planococcyl diphosphate, this is the first example of an efficient enzymatic synthesis. Rational design of the protein allowed for a considerable increase of the irregular activity. The engineered enzyme can be implicated in the sustainable production of insect
