Expert Solution & Answer
Answer to Problem 1P
The function of aspartate transcarbamoylase is to convert aspartate and carbamoyl phosphate into the compound, N-carbamoylaspartate and inorganic phosphate.
Explanation of Solution
The enzyme, aspartate transcarbamoylase contains two polypeptides which are having different roles. The first polypeptide chain works as a catalytic subunit that helps in carrying the amino acid carbamylation. The second polypeptide chain works as a regulatory subunit. This second polypeptide possesses regulatory sites.
Thus, the enzyme, aspartate transcarbamoylase helps in the condensation of aspartate and carbamoyl phosphate into the compound, N-carbamoylaspartateand also into the inorganic phosphate.

- Recall that phosphonacetyl L - aspartate (PALA) is a potent inhibitor of ATCase because it mimics the two physiological substrates. However, in the presence of substrates, low concentrations of this unreactive bisubstrate analog increase the reaction velocity. On the addition of PALA, the reaction rate increases until an average of three molecules of PALA are bound per molecule of enzyme. This maximal velocity is 17-fold greater than it is in the absence of PALA. The reaction rate then decreases to nearly zero on the addition of three more molecules of PALA per molecule of enzyme. Why do low concentrations of PALA activate ATCase?arrow_forwardThe allosteric properties of aspartate transcarbamoylase have been discussed in detail in this chapter.
