EC 1.3.8.2

Names

Accepted name:
4,4'-diapophytoene desaturase (4,4'-diapolycopene-forming)
Other names:
dehydrosqualene desaturase [ambiguous]
CrtN [ambiguous]
4,4'-diapophytoene:FAD oxidoreductase [ambiguous]
15-cis-4,4'-diapophytoene:FAD oxidoreductase
4,4'-diapophytoene desaturase [ambiguous]
Systematic name:
15-cis-4,4'-diapophytoene:FAD oxidoreductase (4,4'-diapolycopene-forming)

Reactions

Comments:

The enzyme catalyses four successive dehydrogenations, resulting in production of 4,4'-diapolycopene. While the enzyme from Staphylococcus aureus was only shown to produce 4,4'-diaponeurosporene in vivo [4], it is able to catalyse the last reaction in vitro [5].
