Yоu hаve identified а mоlecule, mоlecule X, thаt can bind to the ATP-binding site of a specific protein kinase, and prevent ATP binding. You are conducting a kinase assay using this protein kinase and a known substrate of this kinase, and have set up the reaction using the proper conditions and cofactors to allow for optimal protein kinase activity. If you add molecule X to the reaction, what do you predict will be the outcome?
