Protein
Ornithine carbamoyltransferase
Gene
argF
Organism
Mycobacterium tuberculosis (strain CDC 1551 / Oshkosh)
Status
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, which is a substrate for argininosuccinate synthetase, the enzyme involved in the final step in arginine biosynthesis.By similarity
Catalytic activityi
- EC:2.1.3.3
: L-arginine biosynthesis Pathwayi
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:
- Ornithine carbamoyltransferase (argF)
- Argininosuccinate synthase (argG)
- Argininosuccinate lyase (argH)
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.
