Arginine biosynthesis bifunctional protein ArgJ

Gene

argJ

Organism
Mycobacterium leprae (strain TN)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Catalyzes two activities which are involved in the cyclic version of arginine biosynthesis: the synthesis of N-acetylglutamate from glutamate and acetyl-CoA as the acetyl donor, and of ornithine by transacetylation between N(2)-acetylornithine and glutamate.UniRule annotation

Catalytic activityi

N(2)-acetyl-L-ornithine + L-glutamate = L-ornithine + N-acetyl-L-glutamate.UniRule annotation
Acetyl-CoA + L-glutamate = CoA + N-acetyl-L-glutamate.UniRule annotation

Pathwayi: L-arginine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-ornithine and N-acetyl-L-glutamate from L-glutamate and N(2)-acetyl-L-ornithine (cyclic).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Arginine biosynthesis bifunctional protein ArgJ (argJ)

Similar proteinsi

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.
