1.1.1.267 1-deoxy-D-xylulose-5-phosphate reductoisomeraseIUBMB Comments
The enzyme requires Mn2+, Co2+ or Mg2+ for activity, with the first being most effective. The enzyme from several eubacteria, including Escherichia coli, forms part of an alternative nonmevalonate pathway for terpenoid biosynthesis (for diagram, {terp/nonMVA}). The mechanism has been shown to be a retroaldol/aldol reaction .

the reaction does not exhibit burst kinetics for either substrate, indicating that product release is not rate-limiting, the rearrangement step, which precedes hydride transfer, is rate-limiting for 1-deoxy-D-xylulose 5-phosphate but becomes partially ratelimiting for 1-fluoro-1-deoxy-D-xylulose 5-phosphate, thus, rearrangement appears to be enhanced by substitution of a hydrogen atom in the methyl group of 1-deoxy-D-xylulose 5-phosphate by fluorine, consistent with a retro-aldol/aldol mechanism for the rearrangement during conversion of 1-deoxy-D-xylulose 5-phosphate to 2-C-methyl-D-erythritol 4-phosphate

a retroaldol/aldol mechanism for the DXR catalyzed rearrangement of 1-deoxy-D-xylulose 5-phosphate to 2-C-methyl-D-erythritol 4-phosphate. DXR first cleaves the C3-C4 bond of 1-deoxy-D-xylulose 5-phosphate in a retroaldol manner to generate a three-carbon and a two-carbon phosphate bimolecular intermediate. These two species are then reunited by an aldol reaction to form a new C-C bond, yielding the same aldehyde intermediate methylerythrose phosphate. Subsequent reduction of methylerythrose phosphate by NADPH affords 2-C-methyl-D-erythritol 4-phosphate

metabolism
the enzyme catalyzes the second regulation step in the 2-C-methyl-D-erythritol 4-phosphate pathway and the the first committed step of the 2-C-methyl-D-erythritol 4-phosphate pathway for isoprenoid biosynthesis
metabolism
-
the 1-deoxy-D-xylulose-5-phosphate reductoisomerase is the second enzyme in the nonmevalonate isoprene biosynthesis pathway, catalyzing the reductive isomerization of 1-deoxy-D-xylulose-5-phosphate to 2-methyl-D-erythritol-4-phosphate for making isopentenyl diphosphate and dimethylallyl diphosphate

metabolism
-
1-deoxy-D-xylulose-5-phosphate, DXP, reductoisomerase catalyzes the first committed step in the 2-C-methyl-D-erythritol 4-phosphate pathway involving a skeletal rearrangement of DXP via a retroaldol/aldol process followed by reduction by NADPH to yield 2-C-methyl-D-erythritol 4-phosphate
metabolism
-
the enzyme is involved in the isoprenoid biosynthetic DOXP/MEP pathway
metabolism
-
the enzyme is involved in a parasite-specific, isoprenoid biosynthetic DOXP/MEP pathway
physiological function
involved in the 2-C-methyl-D-erythritol 4-phosphate pathway
physiological function
-
a dxr gene T-DNA insertion mutant shows albino and dwarf phenotype. The mutant does not bolt, has a significantly reduced number of trichomes and most of the stomata cannot close normally in the leaves. Two transgenic co-suppression lines produce more yellow inflorescences and albino sepals with no trichomes. The transcription levels of genes involved in trichome initiation are strongly affected in the mutants. Exogenous application of gibberellic acid GA3 can partially rescue the dwarf phenotype and the trichome initiation of the insertion mutant, and exogenous application of abscisic acid can rescue the stomata closure defect
physiological function
-
1-deoxy-D-xylulose-5-phosphate reductoisomerase in the non-mevalonate isoprene biosynthesis pathway is essential to the organism
physiological function
-
in transgenic spike lavender plants (Lavandula latifolia) constitutively expressing the Arabidopsis thaliana DXR gene, a clear correlation between transcript accumulation and monoterpene production cannot be established. The DXR enzyme does not play a crucial role in the synthesis of plastidial monoterpene precursors

two substrate-binding domains, LPADSEHSAI and NKGLEVIEAHY, locate in its mid-region of the enzyme molecule, which is highly homologous to DXRs from other plants and similar to the DXR from Escherichia coli
