View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-alanine and anthranilate from L-kynurenine, the pathway L-kynurenine degradation and in Amino-acid degradation.

Pathwayi: NAD(+) biosynthesis

This protein is involved in step 2 of the subpathway that synthesizes quinolinate from L-kynurenine.UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Kynurenine 3-monooxygenase (bna4)
  2. Kynureninase 1 (bna5-1), Kynureninase 2 (bna5-2)
  3. 3-hydroxyanthranilate 3,4-dioxygenase 1 (bna1-1), 3-hydroxyanthranilate 3,4-dioxygenase 2 (bna1-2)
This subpathway is part of the pathway NAD(+) biosynthesis, which is itself part of Cofactor biosynthesis.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
