β-carotene 3,3'-monooxygenase CrtZ |
Description | Requires ferredoxin and Fe(II). Also acts on other carotenoids with a β-end group. In some species canthaxanthin is the preferred substrate. Reaction: β-carotene + 2 NADH + 2 H+ + 2 O2 = zeaxanthin + 2 NAD+ + 2 H2O(overall reaction); (1a) β-carotene + NADH + H+ + O2 = β-cryptoxanthin + NAD+ + H2O; (1b) β-cryptoxanthin + NADH + H+ + O2 = zeaxanthin + NAD+ + H2O |
