question 37

Multiple Choice

You have identified a molecule,molecule X,that 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?

• A)The substrate will be phosphorylated normally in the presence of molecule X.
• B)Less phosphorylation of the substrate will be seen in the presence of molecule X.
• C)More phosphorylation of the substrate will be seen in the presence of molecule X.
