| - | + | [https://www.uniprot.org/uniprot/AURF_STRTU AURF_STRTU] Involved in the biosynthesis of the polyketide antibiotic aureothin (PubMed:14700630, PubMed:15038705). Catalyzes the oxidation of p-aminobenzoate (pABA) to p-nitrobenzoate (pNBA), an unusual polyketide synthase starter unit (PubMed:15038705, PubMed:16927313, PubMed:20798054, PubMed:18458342). Reaction mechanism involves the generation of a peroxodiiron(III/III) intermediate, which effects the initial oxidation of p-aminobenzoate to p-hydroxylaminobenzoate (Ar-NHOH) (PubMed:19731912, PubMed:20798054). Ar-NHOH is then probably directly converted to the fully oxidized p-nitrobenzoate via a four-electron N-oxidation, bypassing the formation of a nitroso compound (PubMed:20798054).<ref>PMID:14700630</ref> <ref>PMID:15038705</ref> <ref>PMID:16927313</ref> <ref>PMID:18458342</ref> <ref>PMID:19731912</ref> <ref>PMID:20798054</ref> | |
