Pathwayi: L-glutamate degradation via mesaconate pathway

This protein is involved in step 1 of the subpathway that synthesizes acetate and pyruvate from L-glutamate.UniRule annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Glutamate mutase sigma subunit (glmS), Glutamate mutase epsilon subunit (glmE)
  2. Methylaspartate ammonia-lyase
  3. no protein annotated in this organism
  4. no protein annotated in this organism
This subpathway is part of the pathway L-glutamate degradation via mesaconate pathway, which is itself part of 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.
