Cytosolic 4-hydroxyphenylpyruvate dioxygenase (HPD) catalyzes the reaction of 3-(4-Hydroxyphenyl)pyruvate with molecular oxygen to form homogentisate and CO2 (Ruetschi et al. 2000, Lindblad et al. 1970). Unpublished crystallographic data indicate that the enzyme is a homodimer (PDB 3ISQ) utilising Fe2+ and ascorbate (AscH-).
