Question

Two examples of allosteric enzymes in glycogen synthesis

Answer 1

Example of an allosteric enzyme is aspartate trascarbamoylase. The enzyme catalyzes the first step in the synthesis of pyrimidines. The enzyme functions to catalyze the condensation of aspartate and carbamoyl phosphate to form Ncarbamoylaspartate and orthophosphate. The enzyme ultimately catalyzes the reaction that will yield cytidine triphosphate (CTP). This allosteric enzyme is unique in that for high products of the final product CTP, the enzyme activity is low. However, for low concentrations of the final product CTP, the enzymatic activity is high.

Another example is phosphofructokinase.
