1-hydroxycarotenoid 3,4-desaturase

inquiry

Cat No.

EXWM-1429

Description

The enzymes from Rubrivivax gelatinosus and Rhodobacter sphaeroides prefer the acyclic carotenoids (e.g. 1-hydroxy-1,2-dihydroneurosporene, 1-hydroxy-1,2-dihydrolycopene) as substrates. The conversion rate for the 3,4-desaturation of the monocyclic 1'-hydroxy-1',2'-dihydro-γ-carotene is lower. The enzyme from the marine bacterium strain P99-3 shows high activity with the monocyclic carotenoid 1'-hydroxy-1',2'-dihydro-γ-carotene. The enzyme from Rhodobacter sphaeroides utilizes molecular oxygen as the electron acceptor in vitro. However, oxygen is unlikely to be the natural electron acceptor under anaerobic conditions.
