Abstract
Chalcone isomerase ( 5.5.1.6 ; also known as chalcone-flavanone isomerase or fatty-acid-binding protein) 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 [ 1 ].
