CC -!- FUNCTION: [Isoform 2]: A cytochrome P450 monooxygenase that catalyzes
CC the 3,4 desaturation of all-trans-retinol (also called vitamin A1) to
CC all-trans-3,4-didehydroretinol (also called vitamin A2) in the skin.
CC Desaturates with lower efficiency all-trans retinal and all-trans
CC retinoic acid. Forms minor amounts of 3-hydroxy and 4-hydroxy all-
CC trans-retinol derivatives. Mechanistically, uses molecular oxygen
CC inserting one oxygen atom into a substrate and reducing the second into
CC a water molecule. Two electrons are provided by NADPH via a two-protein
CC mitochondrial transfer system comprising flavoprotein FDXR
CC (adrenodoxin/ferredoxin reductase) and nonheme iron-sulfur protein FDX1
CC or FDX2 (adrenodoxin/ferredoxin). {ECO:0000269|PubMed:27059013,
