context_page_description: Tryptophan 7-halogenase is an enzyme with systematic name L-tryptophan:FADH2 oxidoreductase. This enzyme catalyses the following chemical reaction:
  tryptophan + FADH₂ + Cl⁻ + O₂ + H⁺ 7-chloro-L-tryptophan + FAD + 2 H₂O
  The enzyme can use bromide ions in place of chloride.
context_section_description: Tryptophan 7-halogenase (EC 1.14.19.9, PrnA, RebH) is an enzyme with systematic name L-tryptophan:FADH2 oxidoreductase (7-halogenating). This enzyme catalyses the following chemical reaction:
  tryptophan + FADH₂ + Cl⁻ + O₂ + H⁺  7-chloro-L-tryptophan + FAD + 2 H₂O
  The enzyme can use bromide ions (Br⁻) in place of chloride (Cl⁻).
