Chorismate is an important precursor for aromatic amino acids

Chorismate is an important precursor for aromatic amino acids

Chorismate is an important precursor for aromatic amino acids. Derived from PEP and erythrose 4-phosphate First branch point of pathways, one leading to tryptophan, another to phenylalanine and tyrosine. Tryptophan biosynthesis requires PRPP, glutamine and serine.
