Recombinant p-hydroxyphenylpyruvate dioxygenase of high activity.
Inhibitors of p-hydroxyphenylpyruvate dioxygenase (HPPD) are bleaching compounds impairing the formation of colored carotenoids. This activity makes them promising candidates for herbicides. Detailed studies on enzyme-inhibitor complexes or on the binding niche of the enzyme have still to be performed. Enzyme preparation from plants is time-consuming and the yield is poor. This paper describes ...
متن کاملp-Hydroxyphenylpyruvate dioxygenase is a herbicidal target site for beta-triketones from Leptospermum scoparium.
p-Hydroxyphenylpyruvate dioxygenase (HPPD) is a key enzyme in tyrosine catabolism and is the molecular target site of beta-triketone pharmacophores used to treat hypertyrosinemia in humans. In plants, HPPD is involved in the biosynthesis of prenyl quinones and tocopherols, and is the target site of beta-triketone herbicides. The beta-triketone-rich essential oil of manuka (Leptospermum scopariu...
متن کاملActivation of ethylene-responsive p-hydroxyphenylpyruvate dioxygenase leads to increased tocopherol levels during ripening in mango
Mango is characterized by high tocopherol and carotenoid content during ripening. From a cDNA screen of differentially expressing genes during mango ripening, a full-length p-hydroxyphenylpyruvate dioxygenase (MiHPPD) gene homologue was isolated that encodes a key enzyme in the biosynthesis of tocopherols. The gene encoded a 432-amino-acid protein. Transcript analysis during different stages of...
متن کاملComplementation of the Arabidopsis pds1 mutation with the gene encoding p-hydroxyphenylpyruvate dioxygenase.
Plastoquinone and tocopherols are the two major quinone compounds in higher plant chloroplasts and are synthesized by a common pathway. In previous studies we characterized two loci in Arabidopsis defining key steps of this biosynthetic pathway. Mutation of the PDS1 locus disrupts the activity of p-hydroxyphenylpyruvate dioxygenase (HPPDase), the first committed step in the synthesis of both pl...
متن کاملPurification and some properties of human 4-hydroxyphenylpyruvate dioxygenase (I).
4-Hydroxyphenylpyruvate dioxygenase (I-hydroxyphenylpyruvate:oxygen oxidoreductase (hydroxylating, decarboxylating), EC 1.13.11.27) has been purified 800-fold in 25% yield from human liver by a procedure involving ammonium sulfate fractionation of an acetone powder extract and chromatography on hydroxylapatite, sulfopropyl-Sephadex C-50, and triethylaminoethyl cellulose. The preparation obtaine...
