Phenylalanine, tyrosine and tryptophan biosynthesis
Aspartate aminotransferase, cytoplasmic isozyme 1
Dopamine + Oxygen + Water → 3,4-Dihydroxyphenylacetaldehyde + Ammonia + Hydrogen peroxide
L-Tyrosine + Oxoglutaric acid → 4-Hydroxyphenylpyruvic acid + L-Glutamic acid
L-Tyrosine → Carbon dioxide + Tyramine
Aspartate aminotransferase, cytoplasmic isozyme 2
