Question
Report the KM and Vmax values for PP1 in the presence and absence of the inhibitor. Aspartate transcarbamoylase (ATCase) catalyzes the formation of N-carbamoyl aspartate from carbamoyl phosphate and aspartate, a step in the multienzyme process that synthesizes cytidine triphosphate (CTP). Kinetic studies of ATCase activity as a function of aspartate concentration yield the results shown in the graph. Is ATCase an allosteric enzyme? How do you know? What kind of an effector is CTP? Explain. What is the biological significance of CTP's effect on ATCase? What kind of an effector is ATP? Explain. What is the biological significance of ATP's effect on ATCase? The activity of ATCase was measured in presence of several nucleotide combinations. The results areExplanation / Answer
a. Yes.Because it is effecting the rate by changing the affinity at different site. They are not directly affecting the activity and but affecting indirectly by binding to other sites.
b.
CTP is decreasing the activity. SO it is negative catalyst or inhibitors.
They decreases the rate of reaction
c.
ATP is increasing the activity.So it is positive catalyst or enzyme.
They increases the rate of reaction
