Flavonoid biosynthesis

Flavonoids, a diverse group of secondary metabolites, are known for their health-promoting properties, including antioxidant, anti-inflammatory, and anticancer activities. Phyllanthus amarus is a medicinal plant with extensive traditional use and it is a rich source of flavonoids. This study aimed to elucidate the gene expression in flavonoid biosynthesis in P. amarus.

A new enzyme,S-adenosyl-L-methionine:flavonoid 4¢-O-methyltransferase (EC 2.1.1.-)(F 4¢-OMT), has been puri-fied 1 399-fold from the tissues of carnation (Dianthus caryophyllus L). The enzyme, with a molecular mass of 43–45 kDa and a pI of 4.15, specifically methylates the hydroxysubstituent in4¢-positionof theflavones, flavanones and isoflavones in the presence ofS-adenosyl-L-methionine. A high affinity for the flavone kaempferol was observed (Km¼1.7lM;Vmax¼95.2lmolÆmin )1 Æmg )1 ), while other 4¢-hydroxylated flavonoids proved likewise to be suitable substrates....
