A multienzyme complex that catalyzes the formation N-carbamoyl-L-aspartate from carbamoyl phosphate and L-aspartate. It exhibits a variety of architectural organizations, but in all microorganisms the core catalytic component is a homotrimer of approximately 34 kDa polypeptides.

Comment
Note that in eukaryotes, aspartate carbamoyltransferase is usually a single polypeptide, not a complex, and should therefore not be annotated to this component term.
