Characterization of Aspen Isoprene Synthase, an Enzyme Responsible for Leaf Isoprene Emission to the Atmosphere [PDF]
Isoprene (2-methyl-1,3-butadiene) is a volatile hydrocarbon emitted from many plant species to the atmosphere, where it plays an important role in atmospheric chemistry. An enzyme extracted from aspen (Populus tremuloides) leaves was previously found to catalyze the Mg(2+)-dependent elimination of pyrophosphate from dimethylallyl diphosphate (DMAPP) to

Leaf Isoprene Emission Rate Is Dependent on Leaf Development and the Level of Isoprene Synthase [PDF]
Isoprene (2-methyl-1,3-butadiene) is a major volatile hydrocarbon produced by many plant species. Here we report that in velvet bean (Mucuna sp.), isoprene emission is strongly dependent on leaf developmental state and that changes in extractable isoprene synthase activity parallel isoprene emission rates during leaf development. Both leaf emission and

Zymomonas mobilis is an industrially relevant aerotolerant anaerobic bacterium that can convert up to 96% of consumed glucose to ethanol. This highly catabolic metabolism could be leveraged to produce isoprenoid-based bioproducts via the methylerythritol

Relationships among Isoprene Emission Rate, Photosynthesis, and Isoprene Synthase Activity as Influenced by Temperature [PDF]
Isoprene emissions from the leaves of velvet bean (Mucuna pruriens L. var utilis) plants exhibited temperature response patterns that were dependent on the plant's growth temperature. Plants grown in a warm regimen (34/28 degrees C, day/night) exhibited a temperature optimum for emissions of 45 degrees C, whereas those grown in a cooler regimen (26/20 ...

Heterologous expression of 2-methylisoborneol / 2 methylenebornane biosynthesis genes in Escherichia coli yields novel C11-terpenes. [PDF]
The structural diversity of terpenoids is limited by the isoprene rule which states that all primary terpene synthase products derive from methyl-branched building blocks with five carbon atoms.

Light-Dependent Isoprene Emission (Characterization of a Thylakoid-Bound Isoprene Synthase in Salix discolor Chloroplasts) [PDF]
Abstract Isoprene synthase is an enzyme that is responsible for the production of the volatile C5 hydrocarbon, isoprene, in plant leaves. Isoprene formation in numerous C3 plants is interesting because (a) large quantities of isoprene are emitted, 5 x 1014 g of C annually, (b) a plant may release 1 to 8% of its fixed C as isoprene, and ...
