1-Hydroxycarotenoid 3,4-desaturase (EC 1.3.99.27, CrtD, hydroxyneurosporene desaturase, carotenoid 3,4-dehydrogenase, 1-hydroxy-carotenoid 3,4-dehydrogenase) is an enzyme with systematic name 1-hydroxy-1,2-dihydrolycopene:acceptor oxidoreductase. This enzyme catalyses the following chemical reaction

1-hydroxy-1,2-dihydrolycopene + acceptor ⇌ 1-hydroxy-3,4-didehydro-1,2-dihydrolycopene + reduced acceptor

The enzymes from Rubrivivax gelatinosus and Rhodobacter sphaeroides acts primarily on acyclic carotenoids.
