Sysname
9-cis-beta-carotene:oxygen oxidoreductase (9',10'-cleaving)
Reaction(IUBMB)
9-cis-beta-carotene + O2 = 9-cis-10'-apo-beta-carotenal + beta-ionone [RN:
R10557 ]
Reaction(KEGG)
Substrate
Product
9-cis-10'-apo-beta-carotenal [CPD:
C20692 ];
beta-ionone [CPD:
C12287 ]
Comment
Requires Fe2+. The enzyme participates in a pathway leading to biosynthesis of strigolactones, plant hormones involved in promotion of symbiotic associations known as arbuscular mycorrhiza.
