WebJan 2, 2024 · Chalcone isomerase (CHI) was a rate-limiting enzyme in flavonoids metabolic pathways. Terpenoids and flavonoids are from different biosynthetic pathways, but there is a synergistic action between them on a variety of biological processes in plants. Here, the full-length cDNA of CHI was isolated from A. annua.
WebChalcone isomerase (CHI; EC 5.5.1.6) is an essential enzyme of the anthocyanins biosynthetic pathway, which catalyzes the intramolecular cyclization of bicyclic chalcones into tricyclic (S)-flavanones. In order to investigate the role of chalcone isomerase in anthocyanins biosynthesis in sweetpotato, we cloned and characterized the chalcone ... WebChalcone isomerase (CHI) catalyzes the intramolecular cyclization of bicyclic chalcones into tricyclic (S)-flavanones. The activity of CHI is essential for the biosynthesis of flavanone precursors of floral pigments and phenylpropanoid plant defense compounds. We have examined the spontaneous and CHI-catalyzed cyclization reactions of 4,2′,4′,6′ …
WebChalcone isomerase (CHI), catalyzing isomerization of chalcones, is a crucial enzyme in flavonoid biosynthesis. Three CHI genes were isolated from Clivia miniata and designated as CmCHI1, CmCHI2 and CmCHI3 , respectively. Multiple sequence alignments and phylogenetic analysis showed that CmCHI1 and CmCHI2 were members of type I CHI … WebOct 21, 2024 · Chalcone isomerase (CHI) family proteins play essential roles in flavonoid biosynthesis but little are known about the transcription factors controlling their gene expression. Here, we identified a type IV CHI (designated as CitCHIL1) from citrus which enhances the accumulation of citrus flavanones and flavones (CFLs).
WebOct 15, 2024 · Chalcone isomerase (CHI) is the second rate-limiting and the first reported enzyme involved in the biosynthetic pathway of flavonoids.
