UniProtKB description: Oxygenase component of a two-component system that utilizes reduced FMN (FMNH2) supplied by the reductase component to catalyze the hydroxylation of 4-hydroxyphenylacetic acid, leading to the production of 3,4-dihydroxyphenylacetate (3,4-DHPA). Also utilizes other reduced flavins such as FADH2 and reduced riboflavin to a lesser extent. Only the compounds with a hydroxyl group in the para (p-) position can be hydroxylated. May also oxidize phenol to catechol, and hydroxylate other phenol derivatives.
