KEGG ENZYME: 5.3.99.8

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.
