Tea leaves are major source of catechins—antioxidant flavonoids. Dihydroflavonol 4-reductase (DFR, EC is one of the important enzymes that catalyzes the reduction of dihydroflavonols to leucoanthocyanins, a key “late” step in the biosynthesis of catechins. This manuscript reports characterization of DFR from tea (CsDFR) that comprised 1,413 bp full-length cDNA with ORF of 1,044 bp (115–1,158) and encoding a protein of 347 amino acids. Sequence comparison of CsDFR with earlier… CONTINUE READING
