The enzyme can insert a hydroxy group into other similar compounds, for example to give 3-dehydro-6-deoxoteasterone. It is a cytochrome P450 protein containing heme, isolated from Arabidopsis thaliana, and requires a partner cytochrome P450 reductase for functional expression. This uses nicotinamide adenine dinucleotide phosphate.[2] 3-Epi-6-deoxocathasterone 23-monooxygenase takes part in brassinosteroid biosynthesis.[3]
