Pathwayi: L-histidine degradation into L-glutamate

This protein is involved in step 3 of the subpathway that synthesizes N-formimidoyl-L-glutamate from L-histidine.UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Histidine ammonia-lyase (hutH)
  2. Urocanate hydratase (hutU)
  3. Imidazolonepropionase (hutI)
This subpathway is part of the pathway L-histidine degradation into L-glutamate, 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 N-formimidoyl-L-glutamate from L-histidine, the pathway L-histidine degradation into L-glutamate and in Amino-acid degradation.

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.
