Characterization of dihydroflavonol 4-reductases for recombinant plant pigment biosynthesis applications
Anthocyanins are colorful plant pigments with promising applications as pharmaceuticals and colorants. In order to engineer efficient pigment biosynthesis in Escherichia coli, the activities of various dihydroflavonol 4-reductases (DFRs) were characterized for the three primary dihydroflavonol substrates. The biochemical assays demonstrated variable DFR activities for dihydroflavonol with one B...
متن کاملDisequilibrium of Flavonol Synthase and Dihydroflavonol-4-Reductase Expression Associated Tightly to White vs. Red Color Flower Formation in Plants
Flower color is the main character throughout the plant kingdom. Though substantial information exists regarding the structural and regulatory genes involved in anthocyanin and flavonol biosynthesis, little is known that what make a diverse white vs. red color flower in natural species. Here, the contents of pigments in seven species from varied phylogenetic location in plants with red and whit...
متن کاملIsolation of Dihydroflavonol 4-Reductase cDNA Clones from Angelonia x angustifolia and Heterologous Expression as GST Fusion Protein in Escherichia coli
Blue Angelonia × angustifolia flowers can show spontaneous mutations resulting in white/blue and white flower colourations. In such a white line, a loss of dihydroflavonol 4-reductase (DFR) activity was observed whereas chalcone synthase and flavanone 3-hydroxylase activity remained unchanged. Thus, cloning and characterization of a DFR of Angelonia flowers was carried out for the first time. T...
متن کاملHeterologous Expression of the Secale cereal Thaumatin-Like Protein in Transgenic Canola Plants Enhances Resistance to Stem Rot Disease
Canola (Brassica napus L.) is an important oilseed crop. A serious problem in cultivation of this crop andyield loss, are due to fungal disease stem rot caused by Sclerotinia sclerotiorum. The pathogenesis-related(PR) proteins have the potential for enhancing resistance against fungal pathogen. Thaumatin-like proteins(TLPs) have been shown to have antifungal activity on variou...
متن کاملHeterologous Expression of Bovine Prochymosin in Pichia pastoris GS115
Objectives: In present research we evaluate the expression of this critical enzyme in a eukaryotic system for future use in cheese industry. Materials and Methods: We have cloned bovine prochymosin gene in methylotrophic yeast, P. pastoris, using pPIC9K as an expression vector. The recombinant plasmid was transformed into the host by electroporation, and it was expre...
