Abstract

Terpenoids are a highly diverse class of natural products that have historically provided a rich source for discovery of pharmacologically active small molecules, such as paclitaxel (Taxol) and artemisinin. Unfortunately, these secondary metabolites are typically produced in low abundance in their host organism, and their isolation consequently suffers from low yields and high consumption of natural resources. Furthermore, chemical synthesis of terpenoids can also be difficult to scale for industrial production. For these reasons, an attractive alternative strategy is to engineer metabolic pathways for production of pharmaceuticals or their precursors in a microbial host such as Escherichia coli. A key step is developing methods to carry out cytochrome P450 (P450)-based oxidation chemistry in vivo. Toward this goal, we have assembled two heterologous pathways for the biosynthesis of plant-derived terpenoid natural products, and we present the first examples of in vivo production of functionalized terpenoids in E. coli at high titer using native plant P450s.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Investigators have concentrated on expressing enzymes from phases 1 and 2 of the artemisinin biosynthetic route in transgenic organisms, including HMGR, FPPS, ADS, and CYP71AV1.

    “To date, investigators have concentrated on expressing the enzymes from phases 1 and 2 of the biosynthetic route to artemisinin in transgenic organisms (see Scheme 9 in Section 3). These have included: HMG-CoA reductase (HMGR) [370]; farnesyl diphosphate synthase (FPPS) [371, 372,373,374]; amorpha-4,11-diene synthase (ADS) [375,376,377]; and the P450 enzyme which oxidises amorpha-4,11-diene to art”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
