  Artificial substrates of medium-chain elongating enzymes, hexaprenyl- and heptaprenyl diphosphate synthases

  摘要：

  We examined the reactivity of 3-alkyl group homologues of farnesyl diphosphate or isopentenyl diphosphate for medium-chain prenyl diphosphate synthases, hexaprenyl diphosphate- or heptaprenyl diphosphate synthase. But-3-enyl diphosphate, which lacks the methyl group at the 3-position of isopentenyl diphosphate, condensed only once with farnesyl diphosphate to give E-norgeranylgeranyl diphosphate by the action of either enzyme. However, norfarnesyl diphosphate was never accepted as an allylic substrate at all. 3-Ethylbut-3-enyl diphosphate also reacted with farnesyl diphosphate giving a mixture of (all-E)-3-ethyl7,11,15-trimethylhexadeca-2,6,10,14-tetraenyl- and (all-E)-3,7-diethyl-11,15,19-trimethylicosa-2,6,10,14,18-pentaenyl diphosphates by hexaprenyl diphosphate synthase. On the other hand, heptaprenyl diphosphate synthase reaction of 3-ethylbut-3-enyl diphosphate with farnesyl diphosphate gave only (all-E)-3-ethyl-7,11,15-trimethylhexadeca-2,6,10,14-tetraenyl diphosphate.

  萜烯及其类似物的模块化化学酶促合成。

  摘要：

  非天然萜类化合物具有作为药物和农用化学品的潜力。然而，它们的化学合成通常是长的，复杂的，并且不易于大规模生产。在这里，我们报告了一种模块化的化学酶法，可以从以定量产量产生的二磷酸化前体中合成萜烯类似物。通过添加异戊二烯基转移酶，法呢基二磷酸（2E，6E）-FDP和（2Z，6Z）-FDP的分离率超过80％。还实现了14,15-二甲基-FDP，12-甲基-FDP，12-羟基-FDP，均-FDP和15-甲基-FDP的合成。这些改性的二磷酸酯与萜烯合酶一起使用，以生产非天然的倍半萜类化学信息素（S）-14,15-二甲基Germacrene D和（S）-12-甲基Germacrene D以及二氢青蒿素醛。

  alcohols into pyrophosphates that could be coupled to downstream isoprenoid biosynthesis. To be successful, each kinase in this pathway should be permissive of a broad range of substrates. For the first time, we have probed the promiscuity of the second enzyme in the ADH pathway-isopentenyl phosphate kinase from Thermoplasma acidophilum-towards a broad range of acceptor monophosphates. Subsequently, we evaluate

  类异戊二烯是一类广泛的天然产物，用途广泛。由于在本质上仅提供了两个用于类异戊二烯生物合成的半萜烯构建基，所以用于制造类异戊二烯及其新的自然衍生物的合成生物学方法受到限制。为了解决这一局限性，人工化学酶促途径（例如依赖酒精的半萜（ADH）途径）可利用连续的激酶将外源性醇转化为焦磷酸，然后再将其与下游的类异戊二烯生物合成相结合。为获得成功，该途径中的每种激酶应允许广泛的底物。首次，我们检测了ADH途径中的第二种酶-嗜酸嗜热菌的异戊烯基磷酸激酶向广泛范围的受体单磷酸的混杂。

• Characterization of Thermophilic Archaeal Isopentenyl Phosphate Kinases

  Archaea synthesize isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), the essential building blocks of isoprenoid compounds, from mevalonate (MVA). However, an analysis of the genomes of several members of the Archaea failed to identify genes for the enzymes required to convert phosphomevalonate (PM) to IPP In eukaryotes. The recent discovery of an isopentenyl kinase (IPK) in Methanocaldococcus jannaschii (MJ) Suggests a new variation of the MVA pathway where PM is decarboxylated to give isopentenyl phosphate (IP), which is phosphorylated to produce IPP. A blast search using the MJ protein as a probe revealed a subfamily of amino acid kinases that include the fosfomycin resistance protein fomA, which deactivates the antibiotic by phosphorylation of its phosphonate residue in a reaction similar to the conversion of IP to IPP. IPK genes were cloned from two organisms identified in the search, Methanothermobacter thermautotrophicus (MTH) and Thermoplasma acidophilum (THA), and the His-tagged recombinant proteins were purified by Ni-NTA chromatography. The enzymes catalyze the reversible phosphorylation of IP by ATP, K-cq = 6.3 +/- 1. The catalytic efficiencies (V/K) of the proteins were similar to 2 x 10(6) M-1 s(-1). In the reverse direction, ADP wits a substrate inhibitor for THA IPK, K-i(ADP) = 58 +/- 6 mu M, but not for MTH IPK. Both enzymes were active over a broad range of pH and temperature. Five compounds, dimethylallyl phosphate, isopentenyl thiolophosphate, 1-butyl phosphate, 3-buten-1-yl phosphate, and geranyl phosphate, were evaluated as alternative substrates for the MTH and THA IP kinases. All of the compounds were phosphorylated, although the catalytic efficiency was low for geranyl phosphate.
