The oxygenation reaction of 2-methyl-3-hydroxypyridine-5-carboxylic acid (MHPC) oxygenase with the substrate, MHPC, was investigated. Two oxygenated flavin intermediates C(4a)-hydroperoxy flavin and C(4a)-hydroxy flavin were found, implying that the enzyme functions similarly to flavoprotein hydroxylases. This finding is supported by the
