ENZYME entry: EC

Accepted Name
4-aminobenzoate N-oxygenase.
Reaction catalysed
4-aminobenzoate + reduced acceptor + 2 O(2) <=> 4-nitrobenzoate + acceptor + 2 H(2)O
  • The enzyme, characterized from the bacterium Streptomyces thioluteus, catalyzes an early step in the biosynthesis of the antibiotic aureothin.
  • It contains a carboxylate-bridged binuclear non-heme iron cluster.
  • The native electron donor has not been identified, but is likely an iron-sulfur protein.
  • The reaction mechanism involves formation of an extremely stable peroxo intermediate that catalyzes three two-electron oxidations via a hydroxylamine and dihydroxylamine intermediates.
  • Cf. EC
