General annotation (Comments)

Function	Catalyzes the hydroxylation of L-kynurenine (L-Kyn) to form 3-hydroxy-L-kynurenine (L-3OHKyn). Required for synthesis of quinolinic acid. Ref.4 Ref.9
Catalytic activity	L-kynurenine + NADPH + O2 = 3-hydroxy-L-kynurenine + NADP+ + H2O.
Cofactor	FAD.
Pathway	Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from L-kynurenine: step 1/3. Ref.4
Subcellular location	Mitochondrion. Ref.5 Ref.6
Miscellaneous	Present with 556 molecules/cell in log phase SD medium. Ref.7 Deletion of BNA4 suppresses the toxicity of a mutant HD/HTT fragment.
Sequence similarities	Belongs to the aromatic-ring hydroxylase family. KMO subfamily.
