Protein

Probable kynurenine--oxoglutarate transaminase BNA3

Gene

BNA3

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA).By similarity

Miscellaneous

Present with 1600 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

L-kynurenine + 2-oxoglutarate = 4-(2-aminophenyl)-2,4-dioxobutanoate + L-glutamate.

Cofactori

Pathwayi: L-kynurenine degradation

This protein is involved in step 1 of the subpathway that synthesizes kynurenate from L-kynurenine.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Aromatic amino acid aminotransferase 2 (ARO9), Probable kynurenine--oxoglutarate transaminase BNA3 (BNA3)
  2. no protein annotated in this organism
This subpathway is part of the pathway L-kynurenine degradation, which is itself part of Amino-acid degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes kynurenate from L-kynurenine, the pathway L-kynurenine degradation and in Amino-acid degradation.
