Aromatic/aminoadipate aminotransferase 1
4-Hydroxyphenylpyruvic acid + L-Glutamic acid → L-Tyrosine + Oxoglutaric acid
4-Hydroxyphenylpyruvic acid + Hydrogen Ion → 4-Hydroxyphenylacetaldehyde + Carbon dioxide
4-Hydroxyphenylacetaldehyde + Hydrogen Ion + NADH → NAD + Tyrosol
NADP + Prephenate → 4-Hydroxyphenylpyruvic acid + Carbon dioxide + NADPH
4-Hydroxyphenylpyruvic acid + L-Alanine ↔ L-Tyrosine + Pyruvic acid
