Abstract
The presence of an indole oxidase (indole: O2 oxidoreductase) was detected in the leaf extracts of Tecoma stans. The end product of the reaction was identified as anthranil. Formylaminobenzaldehyde, and o- aminobenzaldehyde were detected as intermediates in the overall conversion. Oxygen-uptake studies established that 3 atoms of oxygen were consumed in the formation of anthranil form I molecule of indole. The enzyme showed an absolute requirement for FAD and Cu2+ for maximum activity. FMN was ineffective as a cofactor. The enzyme had an optimum pH of 5.0. Inhibition studies with GSH and p-chloromericuribenzoate showed that a sulfhydrylcupric-ion complex at the active centre is highly essential.
