General annotation (Comments)

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 By similarity. HAMAP-Rule MF_01109

Catalytic activity

Carbamoyl phosphate + L-ornithine = phosphate + L-citrulline. HAMAP-Rule MF_01109

Pathway

Amino-acid biosynthesis; L-arginine biosynthesis; L-arginine from L-ornithine and carbamoyl phosphate: step 1/3. HAMAP-Rule MF_01109

Subcellular location

Cytoplasm By similarity.

Sequence similarities

Belongs to the ATCase/OTCase family.
