Protein

Ornithine carbamoyltransferase, catabolic

Gene

arcB

Organism
Lactobacillus sakei
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline.By similarity

Catalytic activityi

Carbamoyl phosphate + L-ornithine = phosphate + L-citrulline.

Pathwayi: L-arginine degradation via ADI pathway

This protein is involved in step 2 of the subpathway that synthesizes carbamoyl phosphate from L-arginine.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Arginine deiminase (arcA), Arginine deiminase (arcA), Arginine deiminase (arcA)
  2. Ornithine carbamoyltransferase, catabolic (arcB)
This subpathway is part of the pathway L-arginine degradation via ADI pathway, 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 carbamoyl phosphate from L-arginine, the pathway L-arginine degradation via ADI pathway 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.
