Both E. coli and calf thymus DNA polymerase can be phosphorylated by cAMP-dependent protein kinase and phosphorylation appears to stimulate the DNA polymerase reaction. Conversely, dephosphorylation of the polymerase molecule, by a protein phosphatase, inhibits the polymerase reaction.
大肠杆菌和小牛胸腺DNA聚合酶都能被环磷酸腺苷（cAMP）依赖性蛋白激酶磷酸化，且磷酸化似乎能刺激DNA聚合酶反应。相反，通过一种蛋白磷酸酶使聚合酶分子去磷酸化会抑制聚合酶反应。
