2-Aminoacrylic acid → 2-iminopropanoate
2-iminopropanoate + Hydrogen Ion + Water → Ammonium + Pyruvic acid
1-(o-carboxyphenylamino)-1'-deoxyribulose 5'-phosphate
(1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate
Coenzyme A + NAD + Pyruvic acid → Acetyl-CoA + Carbon dioxide + NADH
1-(o-carboxyphenylamino)-1'-deoxyribulose 5'-phosphate + Hydrogen Ion → (1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate + Carbon dioxide + Water
Chorismate + L-Glutamine → 2-Aminobenzoic acid + Hydrogen Ion + L-Glutamic acid + Pyruvic acid
N-(5-phosphoribosyl)-anthranilate → 1-(o-carboxyphenylamino)-1'-deoxyribulose 5'-phosphate
2-Aminobenzoic acid + Phosphoribosyl pyrophosphate → N-(5-phosphoribosyl)-anthranilate + Pyrophosphate
(1S,2R)-1-C-(indol-3-yl)glycerol 3-phosphate → D-Glyceraldehyde 3-phosphate + Indole
Indole + L-Serine → L-Tryptophan + Water
L-Tryptophan → 2-Aminoacrylic acid + Hydrogen Ion + Indole
