Accepted name: indolin-2-one monooxygenase
Reaction: indolin-2-one + [reduced NADPH—hemoprotein reductase] + O2 = 3-hydroxyindolin-2-one + [oxidized NADPH—hemoprotein reductase] + H2O
Other name(s): BX3 (gene name); CYP71C2 (gene name)
Systematic name: indolin-2-one,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (3-hydroxylating)
Comments: A cytochrome P-450 (heme-thiolate) protein. The enzyme is involved in the biosynthesis of protective and allelophatic benzoxazinoids in some plants, most commonly from the family of Poaceae (grasses).
