EC 1.14.13.168     
Accepted name: indole-3-pyruvate monooxygenase
Reaction: (indol-3-yl)pyruvate + NADPH + H+ + O2 = (indol-3-yl)acetate + NADP+ + H2O + CO2

Glossary: (indol-3-yl)pyruvate = 3-(1H-indol-3-yl)-2-oxopropanoate, (indol-3-yl)acetate = 2-(1H-indol-3-yl)acetate = indole-3-acetate
Other name(s): YUC2 (gene name); spi1 (gene name)
Systematic name: indole-3-pyruvate,NADPH:oxygen oxidoreductase (1-hydroxylating, decarboxylating)
Comments: This plant enzyme, along with EC 2.6.1.99 L-tryptophan—pyruvate aminotransferase, is responsible for the biosynthesis of the plant hormone indole-3-acetate from L-tryptophan.
