Biosynthesis of plant pigments: anthocyanins, betalains and carotenoids.
TLDR
Three classes of pigments act as visible signals to attract insects, birds and animals for pollination and seed dispersal, and protect plants from damage caused by UV and visible light. Expand
A UDP-Glucose:Isoflavone 7-O-Glucosyltransferase from the Roots of Soybean (Glycine max) Seedlings
TLDR
The results led to the proposal that GmIF7GT utilizes a strategy of catalysis that is distinct from those proposed for UGT71G1 and VvGT1, and suggest that an acidic residue at position 392 is very important for primary catalysis of Gmif7GT. Expand
Identification of the glucosyltransferase that mediates direct flavone C‐glucosylation in Gentiana triflora
TLDR
A good correlation was observed between GtUF6CGT1 expression and C‐glycosylflavone accumulation in leaves and petals, and it is reported that this is the first reported C‐glucosyltransferase that mediates direct C‐ GLUCosylation of the flavone skeleton. Expand
Indicated detection of two unapproved transgenic rice lines contaminating vermicelli products.
TLDR
The Bacillus thuringiensis (Bt) rice line, which has a construct similar to the GM Shanyou 63 line, was detected in some vermicelli products by identification of the junction region sequence between rice Act1 promoter and the Cry1Ac gene. Expand
A Novel Glucosylation Reaction on Anthocyanins Catalyzed by Acyl-Glucose–Dependent Glucosyltransferase in the Petals of Carnation and Delphinium[C][W]
TLDR
A phylogenetic analysis of the amino acid sequences suggested that other plant species are likely to have similar acyl-glucose–dependent glucosyltransferases, which typically act as β-glycosidases. Expand
Isolation and characterization of cDNAs encoding an enzyme with glucosyltransferase activity for cyclo-DOPA from four o'clocks and feather cockscombs.
TLDR
Phylogenetic analysis of the amino acid sequences deduced from the cDNAs show that they represent a single subclade distinct from those of other phenylpropanoid and flavonoid glucosyltransferases. Expand
Detection of DOPA 4,5-dioxygenase (DOD) activity using recombinant protein prepared from Escherichia coli cells harboring cDNA encoding DOD from Mirabilis jalapa.
TLDR
This is the first report showing biochemical evidence for DOD activity in vitro showing the formation of betalamic acid from DOPA under suitable assay conditions using recombinant MjDOD produced by Escherichia coli. Expand
Acyl-glucose-dependent glucosyltransferase catalyzes the final step of anthocyanin formation in Arabidopsis.
TLDR
The present study provides the first evidence that an AAGT of Arabidopsis can conjugate a glucose to an acyl moiety of an anthocyanin modified with sugars and organic acids. Expand
p-Hydroxybenzoyl-Glucose Is a Zwitter Donor for the Biosynthesis of 7-Polyacylated Anthocyanin in Delphinium[W]
TLDR
The question of which enzyme activities are necessary for catalyzing the transfer of Glc and pHBA moieties to 7-glucosylated anthocyanin was sought and it was found that these transfers were catalyzed by enzymes that use p-hydroxybenzoyl-Glc (pHBG) as a bifunctional acyl and glucosyl donor. Expand
Detection of UDP–glucose:cyclo‐DOPA 5‐O‐glucosyltransferase activity in four o'clocks (Mirabilis jalapa L.)
TLDR
Results indicate that the glucose moiety of betanin is introduced at the cyclo‐DOPA step, which is followed by condensation with betalamic acid, and not at the betanidin aglycone step. Expand
