Capsanthin/capsorubin synthase explained

Capsanthin/capsorubin synthase
Ec Number:	5.3.99.8
Cas Number:	162032-85-1

Capsanthin/capsorubin synthase (CCS, ketoxanthophyll synthase, capsanthin-capsorubin synthase) is an enzyme with systematic name violaxanthin—capsorubin isomerase (ketone-forming).^{[1] [2] [3]} This enzyme catalyses the following chemical reaction

\rightleftharpoons capsorubin\rightleftharpoons capsanthin

This multifunctional enzyme is induced during chromoplast differentiation in plants.
