For each of the statements below about the dUTPase enzyme, mark whether it is true or false. If it is false, change the language to make the statement true.
_______If the dUTPase enzyme is the rate determining step in a larger metabolic pathway, the reaction likely lies near to equilibrium and is irreversible.
_______For the dUTPase reaction, it is not likely that DG’ = DG°’
_______ dUTPase has a higher affinity for its substrate than for its product, but both of these are higher than the affinity for the transition state
_______Kinetic analysis of dUTPase using Michaelis-Menten methods assumes that the formation of the E*S complex has a large negative value for DG
