CC   -!- PATHWAY: Amino-acid degradation; L-kynurenine degradation; L-alanine
CC       and anthranilate from L-kynurenine: step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_03017}.
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; quinolinate from
CC       L-kynurenine: step 2/3. {ECO:0000255|HAMAP-Rule:MF_03017}.
