CC   -!- PATHWAY: Amino-acid degradation; L-kynurenine degradation; L-
CC       alanine and anthranilate from L-kynurenine: step 1/1.
CC       {ECO:0000255|HAMAP-Rule:MF_01970}.
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate
CC       from L-kynurenine: step 2/3. {ECO:0000255|HAMAP-Rule:MF_01970}.
