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
9-cis-beta-carotene [CPD:C20484];
O2 [CPD:C00007]
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.
