When compared with the T state of aspartate transcarbamoylase,the R state A) has dissociated into two C₃R₃complexes. B) has greater separation of the catalytic subunits. C) is bound to CTP. D) has substrate bound in the ATP binding site.

Question

Quizplus · Accepted Answer

In the R state, the catalytic subunits are separated further apart than in the T state. Option A is incorrect because dissociating into two complexes is not a characteristic of the R state. Option C is incorrect because CTP is a negative allosteric regulator that stabilizes the T state. Option D is incorrect because the ATP binding site is present on the regulatory subunits, not the catalytic subunits.
