KEGG   ENZYME: 1.13.11.67
Entry
EC 1.13.11.67               Enzyme                                 
Name
8'-apo-beta-carotenoid 14',13'-cleaving dioxygenase;
8'-apo-beta-carotenol:O2 oxidoreductase (14',13'-cleaving)
Class
Oxidoreductases;
Acting on single donors with incorporation of molecular oxygen (oxygenases);
With incorporation of two atoms of oxygen
Sysname
8'-apo-beta-carotenol:oxygen oxidoreductase (14',13'-cleaving)
Reaction(IUBMB)
8'-apo-beta-carotenol + O2 = 14'-apo-beta-carotenal + an uncharacterized product
Reaction(KEGG)
(other) R08889
Substrate
8'-apo-beta-carotenol [CPD:C06733];
O2 [CPD:C00007]
Product
14'-apo-beta-carotenal [CPD:C06734];
uncharacterized product
Comment
A thiol-dependent enzyme isolated from rat and rabbit. Unlike EC 1.13.11.63, beta-carotene-15,15'-dioxygenase, it is not active towards beta-carotene. The secondary product has not been characterized, but may be (3E,5E)-7-hydroxy-6-methylhepta-3,5-dien-2-one.
History
EC 1.13.11.67 created 2000 as EC 1.13.12.12, transferred 2012 to EC 1.13.11.67
