General annotation (Comments)

Catalytic activity	4-hydroxyphenylpyruvate + O2 = homogentisate + CO2.
Cofactor	Binds 1 iron ion per subunit By similarity.
Pathway	Amino-acid degradation; L-phenylalanine degradation; acetoacetate and fumarate from L-phenylalanine: step 3/6.
Subunit structure	Homodimer.
Involvement in disease	Defects in HPD are the cause of tyrosinemia type 3 (TYRO3) [MIM:276710]. TYRO3 is an inborn error of metabolism characterized by elevations of tyrosine in the blood and urine, seizures and mild mental retardation. Ref.7 Ref.8 Defects in HPD are a cause of hawkinsinuria (HAWK) [MIM:140350]. HAWK is an inborn error of tyrosine metabolism characterized by failure to thrive, persistent metabolic acidosis, fine and sparse hair, and excretion of the unusual cyclic amino acid metabolite, hawkinsin, in the urine. Ref.8
Sequence similarities	Belongs to the 4HPPD family.
