Homologous Superfamily

Chalcone isomerase, orthogonal bundle domain superfamily (IPR016089)

Short name: Chalcone_isomerase_bundle_sf

Overlapping entries


Chalcone isomerase (EC:; also known as chalcone-flavanone isomerase) is a plant enzyme responsible for the isomerisation of chalcone to naringenin, a key step in the biosynthesis of flavonoids. The Petunia hybrida (Petunia) genome contains two genes coding for very similar enzymes, ChiA and ChiB, but only the first seems to encode a functional chalcone isomerase. This superfamily represents an alpha-helical orthogonal bundle subdomain found in chalcone isomerases [PMID: 10966651].
