Sub-reaction of:
1.3.8.2: 15-cis-4,4'-diapophytoene + 4 FAD + 4 H+ = all-trans-4,4'-diapolycopene + 4 FADH2 ,
1.3.8.o: 15-cis-4,4'-diapophytoene + 3 FAD + 3 H+ = all-trans-4,4'-diaponeurosporene + 3 FADH2

In Pathway: staphyloxanthin biosynthesis , 4,4'-diapolycopenedioate biosynthesis

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.
