Reactions known to consume the compound:

DIBOA-glucoside biosynthesis :
indole + NAD(P)H + oxygen + H+ → indolin-2-one + NAD(P)+ + H2O

indican biosynthesis , indigo biosynthesis :
indole + 2 NADH + oxygen → cis-indole-2,3-dihydrodiol + 2 NAD+

indole degradation to anthranil and anthranilate :
indole + oxygen → 2-formylaminobenzaldehyde

tryptophan biosynthesis :
L-serine + indole → L-tryptophan + H2O

Not in pathways:
indole + NADH + oxygen + H+ → indoxyl + NAD+ + H2O

Reactions known to both consume and produce the compound:

DIBOA-glucoside biosynthesis , tryptophan biosynthesis :
(1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate ↔ indole + D-glyceraldehyde 3-phosphate

tryptophan degradation II (via pyruvate) :
L-tryptophan ↔ indole + 2-aminoprop-2-enoate + H+

Not in pathways:
indole-3-carboxylate + H+indole + CO2

In Reactions of unknown directionality:

Not in pathways:
L-tryptophan + H2O = indole + pyruvate + ammonium
