Entry
EC 1.13.11.69               Enzyme                                 

Name
carlactone synthase;
CCD8 (gene name);
MAX4 (gene name);
NCED8 (gene name)
Class
Oxidoreductases;
Acting on single donors with incorporation of molecular oxygen (oxygenases);
With incorporation of two atoms of oxygen
BRITE hierarchy
Sysname
9-cis-10'-apo-beta-carotenal:oxygen oxidoreductase (14,15-cleaving, carlactone-forming)
Reaction(IUBMB)
9-cis-10'-apo-beta-carotenal + 2 O2 = carlactone + (2E,4E,6E)-7-hydroxy-4-methylhepta-2,4,6-trienal [RN:R10558]
Reaction(KEGG)
Substrate
9-cis-10'-apo-beta-carotenal [CPD:C20692];
O2 [CPD:C00007]
Product
carlactone [CPD:C20693];
(2E,4E,6E)-7-hydroxy-4-methylhepta-2,4,6-trienal [CPD:C20694]
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. Also catalyses EC 1.13.11.70, all-trans-10'-apo-beta-carotenal 13,14-cleaving dioxygenase, but 10-fold slower.
History
EC 1.13.11.69 created 2012
Pathway
ec00906  Carotenoid biosynthesis
ec01110  Biosynthesis of secondary metabolites
Orthology
K17913  carlactone synthase / all-trans-10'-apo-beta-carotenal 13,14-cleaving dioxygenase
