Entry

EC 1.14.14.157              Enzyme

Name

indolin-2-one monooxygenase;
BX3 (gene name);
CYP71C2 (gene name)

Class

Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With reduced flavin or flavoprotein as one donor, and incorporation of one atom of oxygen into the other donor

Sysname

Comment

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).
