Indole-3-pyruvate monooxygenase

Indole-3-pyruvate monooxygenase (EC 1.14.13.168, YUC2 (gene), spi1 (gene)) is an enzyme with systematic name indole-3-pyruvate,NADPH:oxygen oxidoreductase (1-hydroxylating, decarboxylating). This enzyme catalyses the following chemical reaction

(indol-3-yl)pyruvate + NADPH + H + O₂

\rightleftharpoons

(indol-3-yl)acetate + NADP + H₂O + CO₂

Indole-3-pyruvate monooxygenase is a plant enzyme.
