9,9'-Dicis-zeta-carotene desaturase explained
| 9,9'-dicis-zeta-carotene desaturase |
| Ec Number: | 1.3.5.6 |
9,9'-dicis-zeta-carotene desaturase (zeta-carotene desaturase, ZDS) is an enzyme with systematic name 9,9'-dicis-zeta-corotene:quinone oxidoreductase.[1] [2] [3] [4] This enzyme catalyses the following chemical reaction
7,9,7',9'-tetracis-
lycopene + 2
quinol (overall reaction)
(1a) 9,9'-dicis-zeta-carotene + a quinone
7,9,9'-tricis-
neurosporene + a quinol
(1b) 7,9,9'-tricis-neurosporene + a quinone
7,9,7',9'-tetracis-lycopene + a quinol
This enzyme is involved in carotenoid biosynthesis in plants and cyanobacteria.
