Terpenoids, also known as isoprenoids, are a large class of natural products consisting of isoprene (C5) units. There are two biosynthetic pathways, the mevalonate pathway [MD:M00095] and the non-mevalonate pathway or the MEP/DOXP pathway [MD:M00096], for the terpenoid building blocks: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The action of prenyltransferases then generates higher-order building blocks: geranyl diphosphate (GPP), farsenyl diphosphate (FPP), and geranylgeranyl diphosphate (GGPP), which are the precursors of monoterpenoids (C10), sesquiterpenoids (C15), and diterpenoids (C20), respectively. Condensation of these building blocks gives rise to the precursors of sterols (C30) and carotenoids (C40). The MEP/DOXP pathway is absent in higher animals and fungi, but in green plants the MEP/DOXP and mevalonate pathways co-exist in separate cellular compartments. The MEP/DOXP pathway, operating in the plastids, is responsible for the formation of essential oil ...

1PPV: A Crystallographic Investigation of Phosphoantigen Binding to Isopentenyl Pyrophosphate/Dimethylallyl Pyrophosphate Isomerase
Isoprene emissions from vegetation have a large effect on atmospheric chemistry and air quality. Bottomup isoprene emission inventories used in atmospheric models are based on limited vegetation information and uncertain land cover data, leading to potentially large errors. Satellite observations of atmospheric formaldehyde (HCHO), a highyield isoprene oxidation product, provide top-down information to evaluate isoprene emission inventories through inverse analyses. Past inverse analyses have however been hampered by uncertainty in the HCHO satellite data, uncertainty in the time- and NOx -dependent yield of HCHO from isoprene oxidation, and coarse resolution of the atmospheric models used for the inversion. Here we demonstrate the ability to use HCHO satellite data from OMI in a high-resolution inversion to constrain isoprene emissions on ecosystemrelevant scales. The inversion uses the adjoint of the GEOSChem chemical transport model at 0.25◦ × 0.3125◦ horizontal resolution to ...

Terpenoids are of high interest as chemical building blocks and pharmaceuticals. In microbes, terpenoids can be synthesized via the methylerythritol phosphate (MEP) or mevalonate (MVA) pathways. Although the MEP pathway has a higher theoretical yield, metabolic engineering has met with little success because the regulation of the pathway is poorly understood. We applied metabolic control analysis to the MEP pathway in Escherichia coli expressing a heterologous isoprene synthase gene (ispS). The expression of ispS led to the accumulation of isopentenyl pyrophosphate (IPP)/dimethylallyl pyrophosphate (DMAPP) and severely impaired bacterial growth, but the coexpression of ispS and isopentenyl diphosphate isomerase (idi) restored normal growth and wild-type IPP/DMAPP levels. Targeted proteomics and metabolomics analysis provided a quantitative description of the pathway, which was perturbed by randomizing the ribosome binding site in the gene encoding 1-deoxyxylulose 5-phosphate synthase (Dxs). Dxs has a
We use 2005-2009 satellite observations of formaldehyde (HCHO) columns from the OMI instrument to infer biogenic isoprene emissions at monthly 1 × 1◦ resolution over the African continent. Our work includes new approaches to remove biomass burning influences using OMI absorbing aerosol optical depth data (to account for transport of fire plumes) and anthropogenic influences using AATSR satellite data for persistent small-flame fires (gas flaring). The resulting biogenic HCHO columns ( HCHO ) from OMI follow closely the distribution of vegetation patterns in Africa. We infer isoprene emission (EISOP ) from the local sensitivity S = HCHO / EISOP derived with the GEOS-Chem chemical transport model using two alternate isoprene oxidation mechanisms, and verify the validity of this approach using AMMA aircraft observations over West Africa and a longitudinal transect across central Africa. Displacement error (smearing) is diagnosed by anomalously high values of S and the corresponding data are ...
Found in all living organisms, terpenoids make up the largest group of natural products and are essential compounds for many major processes, including photosynthesis, respiration, hormone production, and electron transport. Additionally, they have commercial and medical value in products including fragrances, cosmetics, and medicines. Terpenoids originate from the five-carbon building blocks isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP), which are synthesized by the mevalonic acid (MVA) and methylerithritol phosphate (MEP) pathways. An alternative MVA pathway was discovered in Archaea with the final two enzymes being phosphomevalonate decarboxylase (MPD) and isopentenyl phosphate kinase (IPK). Even though this alternative pathway is not present in plants, presence of IPK was retained. The overexpression of IPK in planta indicates that IPK plays a significant role in the MVA pathway by synthesizing IPP/DMAPP from an IP/DMAP pool for terpenoid biosynthesis. It has been suggested
To address an increasingly severe energy crisis and its environmental consequences, biofuels and biochemicals generated from renewable resources, as a source of fossil fuels and chemicals, could serve as promising alternatives for petroleum [1, 2]. Isoprene becomes increasingly important as a vital platform chemical for the production of synthetic rubber [3] and aviation fuel [4].. So far, dimethylallyl diphosphate, the precursor of isoprene can be produced mainly through two different pathways, the methylerythritol 4-phosphate (MEP) pathway and mevalonate (MVA) pathway [5], which have already been adopted by different research groups for the biosynthesis of isoprene in E. coli [6-10]. The data show that MVA pathway is more effective in the isoprene production than the MEP pathway because of the regulatory mechanisms for the MEP pathway present in the native host [11].. Isoprene biosynthesis using the MVA pathway requires eight reactions that are catalyzed by seven or eight enzymes encoded by ...
Isoprene is synthesized and emitted in large amounts by a number of plant species, especially oak (Quercus sp.) and aspen (Populus sp.) trees. It has been suggested that isoprene improves thermotolerance by helping photosynthesis cope with high temperature. However, the evidence for the thermotolerance hypothesis is indirect and one of three methods used to support this hypothesis has recently been called into question. More direct evidence required new methods of controlling endoge- nous isoprene. An inhibitor of the deoxyxylulose 5-phosphate pathway, the alternative pathway to the mevalonic acid pathway and the pathway by which isoprene is made, is now available. Fosmidomycin eliminates isoprene emission without affecting photosynthesis for several hours after feeding to detached leaves. Photosynthesis of fosmidomycin-fed leaves recovered less following a 2-min high-temperature treatment at 46°C than did photosynthesis of leaves fed water or fosmidomycin-fed leaves in air supplemented with isoprene.

1NFS: Catalytic Mechanism of Escherichia coli Isopentenyl Diphosphate Isomerase Involves Cys-67, Glu-116, and Tyr-104 as Suggested by Crystal Structures of Complexes with Transition State Analogues and Irreversible Inhibitors
Enzymes containing flavin cofactors are predominantly involved in redox reactions in numerous cellular processes where the protein environment modulates the chemical reactivity of the flavin to either transfer one or two electrons. Some flavoenzymes catalyze reactions with no net redox change. In these reactions, the protein environment modulates the reactivity of the flavin to perform novel chemistries. Recent mechanistic and structural data supporting novel flavin functionalities in reactions catalyzed by chorismate synthase, type II isopentenyl diphosphate isomerase, UDP-galactopyranose mutase, and alkyl-dihydroxyacetonephosphate synthase are presented in this review. In these enzymes, the flavin plays either a direct role in acid/base reactions or as a nucleophile or electrophile. In addition, the flavin cofactor is proposed to function as a
Abstract. Using a Large-Eddy Simulation model, we have systematically studied the inability of boundary layer turbulence to efficiently mix reactive species. This creates regions where the species are accumulated in a correlated or anti-correlated way, thereby modifying the mean reactivity. We quantify this modification by the intensity of segregation, IS, and analyse the driving mechanisms: heterogeneity of the surface moisture and heat fluxes, various background wind patterns and non-uniform isoprene emissions. The heterogeneous surface conditions are characterized by cool and wet forested patches with high isoprene emissions, alternated with warm and dry patches that represents pasture with relatively low isoprene emissions. For typical conditions in the Amazon rain forest, applying homogeneous surface forcings and in the absence of free tropospheric NOx, the isoprene-OH reaction rate is altered by less than 10%. This is substantially smaller than the previously assumed IS of 50% in recent ...
Formally, in biosynthesis of terpenes, two or more isoprene molecules are linked to one another. Linking between two isoprene molecules could occur in three ways, given that the head and the tail of the molecule are primarily involved in the linking:. 1. The head of one isoprene molecule could link with the head of another isoprene molecule.. ...
IS (I) superfamily members typically catalyze condensation of isoprenoid units through metal assisted dissociation of pyrophosphate to generate a carbocation intermediate (Figure IS3). Condensation of the carbocation with an allylic acceptor and subsequent loss of a proton results 1 of 4 different connectivity patterns, and an additional 4 can be formed via rearrangement of a common intermediate (Figure IS3). Standard nomenclature to describe the product (e.g.1-4 and c1-2-3) is based on the structures of the hemiterpenes dimethylallyl diphosphate (DMAPP) and isopentenyl diphosphate (IPP) and assigns the prime designation to the donor (carbocation) unit to distinguish it from the acceptor (allylic) unit. Linear chain elongation products synthesized by members of the IS (I) superfamily include C10-50 all-trans isoprenoid diphosphates such as the prototypical C15 product, farnesyl diphosphate. Examples of cyclopropyl formation occur in members involved in sterol and carotenoid biosynthesis where ...

Monoterpene and isoprene emission rates of 15 Eucalyptus species were measured using an air exchange chamber technique and GC-FID analysis. The normalised monoterpene emission rates (leaf temperature 30°C) of these Eucalyptus species ranged from zero for E. forrestiana to 5.4±2.2 μg g−1 h−1 (or 871±33 μg m−2 h−1) for E. globulus. The dominant monoterpene compounds emitted from these Eucalyptus species were α-pinene, 1,8-cineole, β-pinene and limonene. The normalised isoprene emission rates (leaf temperature 30°C, PAR flux 1000 μmol m−2 s−1) ranged from 5.3±1.6 (E. botryoides) to 69±34 μg g−1 h−1 (E. globulus) or from 0.74 (E. cladocalyx) to 9.5 mg m−2 h−1 (E. rudis). Based on monoterpene emission rate data from four Eucalyptus species (E. globulus, E. robusta, E. rudis, and E. sargentii), there were clear exponential relationships between leaf temperature and monoterpene emission rate for these Eucalyptus species. The mean exponential value (β value) of the four ...
Osteoporosis and low bone mass are currently estimated to be a major public health risk affecting |50% of the female population over the age of 50. Because of their bone-selective pharmacokinetics, nitrogen-containing bisphosphonates (N-BPs), currently used as clinical inhibitors of bone-resorption diseases, target osteoclast farnesyl pyrophosphate synthase (FPPS) and inhibit protein prenylation. FPPS, a key branchpoint of the mevalonate pathway, catalyzes the successive condensation of isopentenyl pyrophosphate with dimethylallyl pyrophosphate and geranyl pyrophosphate. To understand the molecular events involved in inhibition of FPPS by N-BPs, we used protein crystallography, enzyme kinetics, and isothermal titration calorimetry. We report here high-resolution x-ray structures of the human enzyme in complexes with risedronate and zoledronate, two of the leading N-BPs in clinical use. These agents bind to the dimethylallyl/geranyl pyrophosphate ligand pocket and induce a conformational change. The

In some embodiments, the reductase is encoded by a nucleic acid construct introduced into the cell. In some embodiments, the IPP isomerase is a Type I isomerase. In some embodiments, the IPP isomerase is a Type II isomerase. In some embodiments,
Diphosphomevalonate decarboxylase (EC 4.1.1.33), most commonly referred to in scientific literature as mevalonate diphosphate decarboxylase, is an enzyme that catalyzes the chemical reaction ATP + (R)-5-diphosphomevalonate ⇌ {\displaystyle \rightleftharpoons } ADP + phosphate + isopentenyl diphosphate + CO2 This enzyme converts mevalonate 5-diphosphate (MVAPP) to isopentenyl diphosphate (IPP) through ATP dependent decarboxylation. The two substrates of this enzyme are ATP and mevalonate 5-diphosphate, whereas its 4 products are ADP, phosphate, isopentenyl diphosphate, and CO2. Mevalonate diphosphate decarboxylase catalyzes the final step in the mevalonate pathway. The mevalonate pathway is responsible for the biosynthesis of isoprenoids from acetate. This pathway plays a key role in multiple cellular processes by synthesizing sterol isoprenoids, such as cholesterol, and non-sterol isoprenoids, such as dolichol, heme A, tRNA isopentenyltransferase, and ubiquinone. This enzyme belongs to the ...
Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. Monoterpenes may be linear (acyclic) or contain rings. Biochemical modifications such as oxidation or rearrangement produce the related monoterpenoids. Biosynthetically, isopentenyl pyrophosphate and dimethylallyl pyrophosphate are combined to form geranyl pyrophosphate. Elimination of the pyrophosphate group leads to the formation of acyclic monoterpenes such as ocimene and the myrcenes. Hydrolysis of the phosphate groups leads to the prototypical acyclic monoterpenoid geraniol. Additional rearrangements and oxidations provide compounds such as citral, citronellal, citronellol, linalool, and many others. Many monoterpenes found in marine organisms are halogenated, such as halomon. In addition to linear attachments, the isoprene units can make connections to form rings. The most common ring size in monoterpenes is a six-membered ring. A classic example is the cyclization of geranyl ...
Terpenoids, or isoprenoids, are a family of compounds with great structural diversity which are essential for all living organisms. In cyanobacteria, they are synthesized from the methylerythritol-phosphate (MEP) pathway, using glyceraldehyde 3-phosphate and pyruvate produced by photosynthesis as substrates. The products of the MEP pathway are the isomeric five-carbon compounds isopentenyl diphosphate and dimethylallyl diphosphate, which in turn form the basic building blocks for formation of all terpenoids. Many terpenoid compounds have useful properties and are of interest in the fields of pharmaceuticals and nutrition, and even potentially as future biofuels. The MEP pathway, its function and regulation, and the subsequent formation of terpenoids have not been fully elucidated in cyanobacteria, despite its relevance for biotechnological applications. In this review, we summarize the present knowledge about cyanobacterial terpenoid biosynthesis, both regarding the native metabolism and ...

Isoprene is no minor player in atmospheric chemistry, Wennberg notes. There is much more isoprene emitted to the atmosphere than all of the gases-gasoline, industrial chemicals-emitted by human activities, with the important exceptions of methane and carbon dioxide, he says. And isoprene only comes from plants. They make hundreds of millions of tons of this chemical . . . for reasons that we still do not fully understand.. Much of the emission of isoprene occurs where anthropogenic emissions are limited, adds Caltech graduate student Fabien Paulot, the papers first author. The chemistry is very poorly understood.. Once released into the atmosphere, isoprene gets oxidized or chewed on by free-radical oxidants such as OH, explains Wennberg. It is this chemistry that is the focus of this new study. In particular, the research was initiated to understand how the oxidation of isoprene can lead to formation of atmospheric particulate matter, so-called secondary organic aerosol. A small ...

Approximately 500 Tg of isoprene are emitted to the atmosphere annually, an amount similar to that of methane, and despite its significant effects on the climate, very little is known about the biological degradation of isoprene in the environment. Isolation and characterisation of isoprene degraders at the molecular level has allowed the development of probes targeting isoA encoding the α-subunit of the isoprene monooxygenase. This enzyme belongs to the soluble diiron centre monooxygenase family and catalyses the first step in the isoprene degradation pathway. The use of probes targeting key metabolic genes is a successful approach in molecular ecology to study specific groups of bacteria in complex environments. Here, we developed and tested a novel isoA PCR primer set to study the distribution, abundance, and diversity of isoprene degraders in a wide range of environments. The new isoA probes specifically amplified isoA genes from taxonomically diverse isoprene-degrading bacteria including members

DeRisi and Ellen Yeh, a postdoctoral fellow in his lab, chose to study an apicoplast pathway that hadnt been targeted yet: a set of genes that synthesize isoprenoids, chemical building blocks with a number of cellular functions. DeRisi and Yeh used a known chemical inhibitor to block the isoprenoid pathway in Plasmodiums apicoplasts. The cells died as expected, indicating that the pathway is vital to their survival. The scientists then added the end product of the pathway-a compound called isopentenyl pyrophosphate(IPP)-to Plasmodiumcells at the same time as the pathway-blocking drug. The malaria-causing cells survived this time, demonstrating the importance of IPP to malaria ...

2 -methylbut-2-ene (2M2B) has a low order of acute toxicity in animals by the dermal and inhalation routes of exposure. It is classifiable as harmful by the oral route of exposure. Non-human data Oral In order to determine the acute oral LD50 of 2M2B a range-finding and definitive study have been performed in albino Wistar rats. In the definitive study, groups of six males and six females were dosed with 1.0, 1.6, 2.5, 4.0, 6.3 and 10 ml/kg. The majority of deaths occurred within the first 3 days following dosing and most survivors had recovered from signs of intoxication by the third day. The author estimated the oral LD50 to be in the range of 1 to 4 ml/kg (i.e., 700 to 2600 mg/kg) (SRC, 1980).
