ENZYME entry: EC 1.14.99.67

Accepted Name
Alpha-N-dichloroacetyl-p-aminophenylserinol N-oxygenase.
Reaction catalysed
Alpha-N-dichloroacetyl-p-aminophenylserinol + reduced acceptor + 2 O(2) <=> chloramphenicol + acceptor + 2 H(2)O
Comment(s)
  • The enzyme, isolated from the bacterium Streptomyces venezuelae, is involved in the biosynthesis of the antibiotic chloramphenicol.
  • It contains a carboxylate-bridged binuclear non-heme iron cluster.
  • The components of the native electron chain have not been identified, although the immediate donor is likely to be an iron-sulfur protein.
  • The reaction mechanism involves formation of an extremely stable peroxo intermediate that catalyzes three individual two-electron oxidations via a hydroxylamine and a nitroso intermediates without releasing the intermediates.
  • Cf. EC 1.14.99.68.
