Construction of Functional Monomeric Type 2 Isopentenyl Diphosphate:Dimethylallyl Diphosphate Isomerase.
Type 2 isopentenyl diphosphate:dimethylallyl diphosphate isomerase (IDI-2) catalyzes the interconversion of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) in the isoprenoid biosynthetic pathway. The enzyme from Streptomyces pneumoniae (spIDI-2) is a homotetramer in solution with behavior, including a substantial increase in the rate of FMN reduction by NADPH in the presence...
متن کاملIDI2, a second isopentenyl diphosphate isomerase in mammals.
We recently described the identification of a novel isopentenyl diphosphate isomerase, IDI2 in humans and mice. Our current data indicate that, in humans, IDI2 is expressed only in skeletal muscle. Expression constructs of human IDI2 in Saccharomyces cerevisiae can complement isomerase function in an idi1-deficient yeast strain. Furthermore, IDI2 has the ability to catalyze the isomerization of...
متن کاملOverexpression of an isopentenyl diphosphate isomerase gene to enhance trans-polyisoprene production in Eucommia ulmoides Oliver
BACKGROUND 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 of higher plants produce latex consisting of cis-polyisoprene. Hevea brasiliensis (rubber tree) produces...
متن کاملFunctional Analysis of the Isopentenyl Diphosphate Isomerase of Salvia miltiorrhiza via Color Complementation and RNA Interference.
Isopentenyl diphosphate isomerase (IPI) catalyzes the isomerization between the common terpene precursor substances isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) during the terpenoid biosynthesis process. In this study, tissue expression analysis revealed that the expression level of the Salvia miltiorrhiza IPI1 gene (SmIPI1) was higher in the leaves than in the roots and ...
متن کاملExpression of an exogenous isopentenyl diphosphate isomerase gene enhances isoprenoid biosynthesis in Escherichia coli.
Escherichia coli expressing the Erwinia carotenoid biosynthesis genes, crtE, crtB, crtI and crtY, form yellow-coloured colonies due to the presence of beta-carotene. This host was used as a visible marker for evaluating regulatory systems operating in isoprenoid biosynthesis of E. coli. cDNAs enhancing carotenoid levels were isolated from the yeast Phaffia rhodozyma and the green alga Haematoco...
