ID 1.14.99.44 DE diapolycopene oxygenase. CA 4 AH2 + all-trans-4,4'-diapolycopene + 4 O2 = 4 A + all-trans- CA 4,4'-diapolycopene-4,4'-dial + 6 H2O. CC -!- Little activity with neurosporene or lycopene. CC -!- Involved in the biosynthesis of C30 carotenoids such as CC staphyloxanthin. CC -!- The enzyme oxidizes each methyl group to the hydroxymethyl and then a CC dihydroxymethyl group, followed by the spontaneous loss of water to CC give an aldehyde group.
