5.5.1.6 (2S)-naringenin - 5.5.1.6 6'-deoxychalcone two isoenzymes act on both 6'-hydroxychalcone and 6'-deoxychalcone and are presumably involved in the legume-specific 6'-deoxyflavonoid pathway, while the other acts only on 6'-hydroxychalcone 5.5.1.6 6'-hydroxychalcone two isoenzymes act on both 6'-hydroxychalcone and 6'-deoxychalcone and are presumably involved in the legume-specific 6'-deoxyflavonoid pathway, while the other acts only on 6'-hydroxychalcone 5.5.1.6 a chalcone - 5.5.1.6 additional information enzyme of anthocyanin biosynthesis 5.5.1.6 additional information light-induced increase in activity, enzyme of phenylpropanoid metabolism 5.5.1.6 additional information enzyme is induced by trans-cinnamic acid 5.5.1.6 additional information involved in biosynthesis of 5-hydroxyflavonoids, 5-deoxyflavonoids and retrochalcone 5.5.1.6 additional information the enzyme catalyzes a step common to the synthesis of flavonoid pigments and isoflavonoid phytoalexins 5.5.1.6 additional information the enzyme plays an important role in flavonoid metabolism 5.5.1.6 additional information elicitor, heat-released from cell walls of the phytopathogenic fungus Colletotrichum lindemuthianum, induces synthesis of both active and inactive chalcone isomerase 5.5.1.6 additional information key enzyme in flavonoid biosynthesis 5.5.1.6 additional information enzyme of the phenylpropanoid pathway 5.5.1.6 additional information UV-light induced increase in activity 5.5.1.6 additional information the enzyme is an essential compound in the biosynthesis of anthocyanin pigments, inducers of Rhizobium nodulation genes, and antimicrobial phytoalexins 5.5.1.6 additional information key role of the enzyme in total flavonoid and apigenin synthesis 5.5.1.6 additional information presence of a premature stop codon in the gold CHI gene results in an inactive chalcone isomerase. Inactivation of chalcone isomerase results in a block in the flavonoid biosynthesis pathway and the accumulation of chalcone derivatives, including a yellow pigment which might be responsible for the unusual gold color in onion 5.5.1.6 additional information the enzyme plays a major part in the cyclization reaction from chalcone to flavanone 5.5.1.6 additional information CHI is involved in the anthocyanin biosynthetic pathway 5.5.1.6 naringenin chalcone - 5.5.1.6 naringenin chalcone i.e. 6'-hydroxychalcone
