Reaction

EC Number Reaction Comment Organism Reaction ID
1.13.11.27 4-hydroxyphenylpyruvate + O2 = homogentisate + CO2 ternary enzyme-substrate complex is firstly decarboxylated to the iron(II)-peracid intermediate followed by heterolytic cleavage of the O-O bond yielding an iron(IV)-oxospecies. This attacks the aromatic ring in C1 position. The arene oxide has no catalytic relevance Pseudomonas fluorescens
