AMP
-
acts as a very potent activator, 20 microM AMP is capable of increasing Xfp2 activity by 24.8%, while 50 microM prevent inhibition caused by 0.6 mM ATP. AMP and phosphoenolpyruvate/oxaloacetic acid operate independently, with AMP activating Xfp2 and phosphoenolpyruvate/oxaloacetic acid inhibiting the activated enzyme
thiamin diphosphate
