Accepted name: | 4,4′-diapophytoene desaturase (4,4′-diapolycopene-forming) | ||||||||||
Reaction: | 15-cis-4,4′-diapophytoene + 4 FAD = all-trans-4,4′-diapolycopene + 4 FADH2 (overall reaction) (1a) 15-cis-4,4′-diapophytoene + FAD = all-trans-4,4′-diapophytofluene + FADH2 (1b) all-trans-4,4′-diapophytofluene + FAD = all-trans-4,4′-diapo-ζ-carotene + FADH2 (1c) all-trans-4,4′-diapo-ζ-carotene + FAD = all-trans-4,4′-diaponeurosporene + FADH2 (1d) all-trans-4,4′-diaponeurosporene + FAD = all-trans-4,4′-diapolycopene + FADH2 |

Other name(s): | 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) | ||||||||||
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]. | ||||||||||
