我们已经发现,双功能AceK激酶/磷酸酶利用逐步添加消除机制,在其去磷酸化反应。这项工作解释了AceK如何与Asp 477和单个Mg(2+)离子一起实现相反的激酶和磷酸酶活性。
We have revealed that bifunctional AceK kinase/phosphatase utilizes a stepwise addition-elimination mechanism in its dephosphorylation reaction. This work explains how AceK enables opposite kinase and phosphatase activities with Asp477 and a single Mg(2+) ion.
