In its second messenger role, cAMP activates enzymes called kinases, whose job is to regulate other enzymes by adding phosphate groups to them.
<h3>What is a kinase?</h3>
A kinase is an enzyme that catalyzes the addition of phosphate group and thus regulates cell signaling.
Moreover, phosphatases are enzyme that catalyze the removal of a phosphate group in a protein.
In conclusion, in its second messenger role, cAMP activates enzymes called kinases, whose job is to regulate other enzymes by adding phosphate groups to them.
