ENZYME entry: EC 1.14.99.68

Accepted Name
4-aminobenzoate N-oxygenase
Reaction catalysed
4-aminobenzoate + AH2 + 2 O2 = 4-nitrobenzoate + A + 2 H2O
Comment(s)
  • 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 1.14.99.67.
