KEGG   ENZYME: 5.3.99.8
Entry
EC 5.3.99.8                 Enzyme                                 
Name
capsanthin/capsorubin synthase;
CCS;
ketoxanthophyll synthase;
capsanthin-capsorubin synthase
Class
Isomerases;
Intramolecular oxidoreductases;
Other intramolecular oxidoreductases
Sysname
violaxanthin---capsorubin isomerase (ketone-forming)
Reaction(IUBMB)
(1) violaxanthin = capsorubin [RN:R07320];
(2) antheraxanthin = capsanthin [RN:R07321]
Reaction(KEGG)
R07320 R07321
Substrate
violaxanthin [CPD:C08614];
antheraxanthin [CPD:C08579]
Product
capsorubin [CPD:C08585];
capsanthin [CPD:C08584]
Comment
This multifunctional enzyme is induced during chromoplast differentiation in plants [1]. Isomerization of the epoxide ring of violaxanthin gives the cyclopentyl-ketone of capsorubin or capsanthin.
