Protein
Ornithine carbamoyltransferase subunit I
Organism
Escherichia coli (strain K12)
Function
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.
Similarity
Belongs to the ATCase/OTCase family.
