Name |
carotenoid-9',10'-cleaving dioxygenase;
BCO2 (gene name);
beta-carotene 9',10'-monooxygenase (misleading);
all-trans-beta-carotene:O2 oxidoreductase (9',10'-cleaving)
|
Class |
Oxidoreductases;
Acting on single donors with incorporation of molecular oxygen (oxygenases);
With incorporation of two atoms of oxygen
|
Sysname |
all-trans-beta-carotene:oxygen oxidoreductase (9',10'-cleaving)
|
Reaction(IUBMB) |
all-trans-beta-carotene + O2 = all-trans-10'-apo-beta-carotenal + beta-ionone [RN: R10559]
|
Reaction(KEGG) |
|
Substrate |
|
Product |
all-trans-10'-apo-beta-carotenal [CPD: C20695];
beta-ionone [CPD: C12287]
|
Comment |
Requires Fe2+. The enzyme catalyses the asymmetric oxidative cleavage of carotenoids. The mammalian enzyme can also cleave all-trans-lycopene.
