Which of the following is not a characteristic of catabolite activator protein (CAP)?
A) it is a positive regulator of the lac operon
B) when the cell has sufficient glucose and lactose, CAP will not be bound to the CAP binding site
C) CAP binding near the promoter site depends on CAP complexation with cAMP
D) the binding of CAP to DNA requires ATP hydrolysis
