A protein complex that catalyzes the formation of carbamoyl phosphate; comprises a small subunit that binds and cleaves glutamine, and a large subunit that accepts the ammonia group cleaved from glutamine, binds all of the remaining substrates and effectors, and carries out all of the other catalytic events.

Comment
Note that in higher eukaryotes, carbamoyl-phosphate synthase is usually a single polypeptide, not a complex, and should therefore not be annotated to this component term.
