the enzyme catalyzes the carbamoylation of L-Asn with a Km of 122 mM and a maximal velocity 10fold lower than observed with the natural substrate, L-Asp. As opposed to L-Asp, no cooperativity is observed with respect to L-Asn

Arg229, which interacts with the beta-carboxylate of L-Asp, plays a critical role in the orientation of L-Asp in the active site and demonstrates the requirement of the beta-carboxylate of L-Asp in the mechanism of domain closure and the allosteric transition in Escherichia coli ATCase

carbamoyl phosphate + L-aspartate
phosphate + N-carbamoyl-L-aspartate
-
upon substrate binding, allosteric Escherichia coli aspartate transcarbamoylase adopts alternate quaternary structures, stabilized by a set of interdomain and intersubunit interactions, which are readily differentiated by their solution x-ray scattering curves. The cooperative binding of aspartate in aspartate transcarbamoylase appears to result from the combination of the preexisting quaternary structure equilibrium with local changes induced by binding of carbamoyl phosphate

carbamoyl phosphate + L-aspartate

there is no preferential partitioning of carbamoyl phosphate between the arginine and pyrimidine biosynthetic pathways. Channeling must occur during the dynamic association of coupled enzymes pairs. The interaction of carbamoyl-phosphate synthetase/aspartate transcarbamoylase is demonstrated by the unexpectedly weak inhibition of the coupled reaction by the bisubstrate analog, N-(phosphonacetyl)-L-aspartate. In the coupled reaction, the effective concentration of carbamoyl phosphate in the vicinity of the aspartate transcarbamoylase active site is 96fold higher than the concentration in the bulk phase. Channeling probably plays an essential role in protecting this very unstable intermediate of metabolic pathways performing at extreme temperatures

CAD is a rate-limiting enzyme required for the formation of UDP sugar, upstream of two different metabolic pathways; the de novo biosynthesis of pyrimidine and pyrimide-based nucleotides, and the formation of UDP sugar intermediates, required for UDP-dependent glycosylation events

the allosteric enzyme shows homotropic cooperative interactions between the catalytic sites for the binding of aspartate due to a quarternary structure transition between high aspartate affinity T state and R state

-
concerted transition between structural and functional states of either low affinity, low activity or high affinity, high activity for aspartate. Addition of ATP along with the substrates increases the rate of the transition from the T to the R state and also decreases the duration of the R-state steady-state phase. Addition of CTP or the combination of CTP/UTP to the substrates significantly decreases the rate of the T-R transition and causes a shift in the enzyme population towards the T state even at saturating substrate concentrations

in the structure of the enzyme trapped in the R state with specific disulfide bonds, two phosphate molecules are bound per active site. The position of the first phosphate corresponds to the position of the phosphate of carbamoyl phosphate and the position of the phosphonate of inhibitor N-phosphonacetyl-L-aspartate. However, the second, more weakly bound phosphate is bound in a positively charged pocket that is more accessible to the surface than the other phosphate. The second phosphate appears to be on the path that phosphate would have to take to exit the active site
