Dimethylallyl diphosphate (DMADP) is a central metabolite in isoprenoid metabolism, but it is difficult to measure. Three different methods for measuring DMADP are compared, and a new method based on the conversion of DMADP to isoprene using recombinant isoprene synthase

Some, but not all, plants emit isoprene. Emission of the related monoterpenes is more universal among plants, but the amount of isoprene emitted from plants dominates the biosphere-atmosphere hydrocarbon exchange. The emission of isoprene from plants affects atmospheric chemistry. Isoprene

Isoprene emission is an important mechanism for improving the thermotolerance of plant photosystems as temperatures increase. In this study, we measured photosynthesis and isoprene emission in trees along an urban-rural gradient that serves as a proxy for climate change, to

Human breath contains hundreds of trace volatile organic compounds. These volatile substances may be generated in the body or may be absorbed as contaminants from the environment. Some of the endogenous substances are characteristic markers of pathophysiological processes and clinicians

A considerable fraction of atmospheric particulate fine matter consists of organosulfates, with some of the most polar ones originating from the oxidation of isoprene. Their structural characterization provides insights into the nature of gas-phase precursors as well as into formation

This review covers the biosynthesis of the starter units of terpenoids, isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) via the nonmevalonate pathway together with a new enzyme involved in the conversion of IPP and DMAPP, i.e type 2 IPP isomerase.

A new homosesterterpene with a unique linear skeleton, named granuloside (1), has been fully characterized from the Antarctic nudibranch Charcotia granulosa Vayssière, 1906 (Mollusca: Gastropoda). The planar structure of 1 was determined by extensive spectroscopic techniques on the methyl derivatives

European deciduous oaks are closely related and are known for their strong emission of volatile isoprenoids. They are chemo-taxonomically diverse, but hybridise frequently. Four-year-old oak seedlings growing together in a model ecosystem facility under near-natural conditions were studied. The leaves

Leaves of some plants emit isoprene, a volatile hydrocarbon. This is formed by a novel chloroplastic isoprenoid biosynthetic pathway, the 1-deoxy-D-xylulose-5-phosphate pathway. The thermoprotection hypothesis suggests that isoprene protects thylakoids from damage at high temperatures. In this article, we discuss

As with 1,3-butadiene (BD), inhalation exposure of B6C3F1 mice to isoprene (2-methyl-1,3-butadiene) caused a macrocytic anemia; induced increases in sister chromatid exchanges in bone marrow cells and in levels of micronucleated erythrocytes in peripheral blood; and produced degeneration of the

The hypothesis was tested that isoprenoids and phenylpropanoids play a prominent role in countering photooxidative stress, following the depletion of antioxidant enzyme activity in plants exposed to severe drought stress under high solar irradiance and high temperatures. Platanus × acerifolia

An engineered Escherichia coli strain was developed for enhanced isoprene production using D-galactose as substrate. Isoprene is a valuable compound that can be biosynthetically produced from pyruvate and glyceraldehyde-3-phosphate (G3P) through the methylerythritol phosphate pathway (MEP). The Leloir and De

Esophagectomy and gastrectomy are associated with profound metabolic changes and significant postoperative morbidity. The aim of this prospective clinical study was to determine whether breath analysis can offer novel insight into the surgical metabolic response and identify biomarkers of postoperative

Bioactive food components (BFACs) represent promising candidates for liver cancer chemoprevention. Among them, isoprenic derivatives (carotenoids, retinoids, perillyl alcohol, limonene, geraniol, farnesol, geranylgeraniol and β- ionone) can be highlighted. The relevance of animal models for the investigation of chemopreventive agents

Breath isoprene accounts for most of the hydrocarbon removal via exhalation and is thought to serve as a non-invasive indicator for assaying several metabolic effects in the human body. The primary objective of this paper is to introduce a novel

1,3-Butadiene, isoprene and chloroprene have all been evaluated more than once by the IARC Monographs Programme on the Evaluation of Carcinogenic Risks to Humans, most recently in February 1998 (Volume 71). Summaries are available on-line at http://monographs.iarc.fr. 1,3-Butadiene is currently

Isoprene (2-methylbuta-1,3-diene) is a large-scale petrochemical used principally in the manufacture of synthetic rubbers. It is also produced by plants and trees and is the major endogenous hydrocarbon formed by mammals, probably from mevalonic acid. Isoprene is metabolised by mammals

Each year, plants emit terragram quantities of the reactive hydrocarbon isoprene (2-methyl-1,3-butadiene) into the earth's atmosphere. In isoprene-emitting plants, the enzyme isoprene synthase (ISPS) catalyzes the production of isoprene from the isoprenoid intermediate dimethylallyl diphosphate (DMADP). While isoprene is emitted

Natural rubber produced by plants, known as polyisoprene, is the most widely used isoprenoid polymer. Plant polyisoprenes can be classified into two types; cis-polyisoprene and trans-polyisoprene, depending on the type of polymerization of the isoprene unit. More than 2000 species

We constructed a biosynthetic pathway of isoprene production in Escherichia coli by introducing isoprene synthase (ispS) from Populus alba. 1-deoxy-D-xylulose 5-phosphate synthase (dxs), 1-deoxy-D-xylulose 5-phosphate reductoisomerase (dxr) and isopentenyl diphosphate (IPP) isomerase (idi) were overexpressed to enhance the isoprene production.
