ATCase perfrorms the first step in CTP synthesis using aspartate as a substrate. It is a wonderful example of allosterism:
a) Describe the quartenary structure of ATCase. To get you started remember that the enzyme consists of two different subunits, of which there are 6 of each for a total of 12 subunits.
b) What are the functions of the two different subunits?
c) what are the allosteric effectors and what is their role in the KM of ATCase?
