A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 1.3.8.2

Accepted Name
4,4'-diapophytoene desaturase (4,4'-diapolycopene-forming).
Alternative Name(s)
4,4'-diapophytoene desaturase.
Dehydrosqualene desaturase.
Reaction catalysed
15-cis-4,4'-diapophytoene + 4 FAD <=> all-trans-4,4'-diapolycopene + 4 FADH(2)
Comment(s)
  • The enzyme catalyzes 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, it is able to catalyze the last reaction in vitro.
