Protein Kinases Are Enzymes That Catalyze Phosphorylation of Target Proteins

question 13

Multiple Choice

Protein kinases are enzymes that catalyze phosphorylation of target proteins at specific sites, whereas protein phosphatases catalyze removal of phosphate(s) from phosphorylated proteins. Phosphorylation and dephosphorylation can function as an on-off switch for a protein's activity, most likely through

• A) the change in a protein's charge leading to a conformational change.

• C) a change in the optimal pH at which a reaction will occur.
• D) a change in the optimal temperature at which a reaction will occur.
• E) the excision of one or more peptides.
