Dihydroflavonol 4-reductase (DFR)
PDZ-Domain
The dihydroflavonol 4-reductase (DFR; EC 1.1.1.219) from the plant Dianthus caryophyllus is an enzyme, catalyzing the reversible conversion of dihydroflavonols e.g. dihydro-kaempferol or dihydroquercetin into their corresponding leucoanthocyanidin. This reaction is NADPH-dependent (Liew et al. 1998) but its counter reaction can also occur with NAD+ instead of NADP+ (Queen Mary University of London 2014). DFR contains 353 amino acids and has a molecular weight of approximately 39.4 kDa. |
