Carotene 7,8-desaturase

From Wikipedia, the free encyclopedia

In enzymology, a carotene 7,8-desaturase (EC 1.14.99.30) is an enzyme that catalyzes the chemical reaction

neurosporene + AH₂ + O₂ lycopene + A + 2 H₂O

The 3 substrates of this enzyme are neurosporene, AH2, and O₂, whereas its 3 products are lycopene, A, and H₂O.

This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derive from O miscellaneous. The systematic name of this enzyme class is carotene,hydrogen-donor:oxygen oxidoreductase. This enzyme is also called zeta-carotene desaturase. This enzyme participates in carotenoid biosynthesis - general.
