What enzyme catalyzes hydrolysis of the second messenger to terminate the message? What is this product called?
Homework Answers
if we consider the secondary messenger like cGMP and cAMP, which are the most common secondary messenger than the phosphodiester bond of cAMP is hydrolyzed by cAMP phosphodiesterase and cGMP phosphodiester bond is hydrolyzed by cGMP phosphodiesterase and the products are 5'AMP and 5'GMP.
