Comments [?]

FUNCTIONCatalyzes the oxidative ring opening of 3-hydroxyanthranilate to 2-amino-3-carboxymuconate semialdehyde, which spontaneously cyclizes to quinolinate.
CATALYTIC ACTIVITY Reaction=3-hydroxyanthranilate + O2 = (2Z,4Z)-2-amino-3-carboxymuconate 6-semialdehyde; Xref=Rhea:RHEA:17953, ChEBI:CHEBI:15379, ChEBI:CHEBI:36559, ChEBI:CHEBI:77612; EC=;
case <FTGroup:1> and <FTGroup:2>
COFACTOR Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Note=Binds 2 Fe(2+) ions per subunit.;
else case <FTGroup:1> or <FTGroup:2>
COFACTOR Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
end case
PATHWAYCofactor biosynthesis; NAD(+) biosynthesis; quinolinate from L-kynurenine: step 3/3.
case <OC:Pseudomonadota>
end case
SIMILARITYBelongs to the 3-HAO family.
