Ornithine carbamoyltransferase

Gene

argF

Organism
Nostoc punctiforme (strain ATCC 29133 / PCC 73102)
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 biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-arginine from L-ornithine and carbamoyl phosphate.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Ornithine carbamoyltransferase (argF)
  2. Argininosuccinate synthase (argG)
  3. Argininosuccinate lyase (argH)
This subpathway is part of the pathway L-arginine biosynthesis, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-arginine from L-ornithine and carbamoyl phosphate, the pathway L-arginine biosynthesis and in Amino-acid 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.
