The bacterial Sec translocase transports unfolded proteins across membranes. In this issue of Structure, Krishnamurthy et al. (2021) report a nexus of conformational dynamics in the translocase motor protein, SecA. Their findings shed light on the Sec activation mechanism and suggest a general role for multi-level dynamics in protein functions.
细菌 Sec 转运蛋白将未折叠的蛋白质穿过膜运输。在本期《结构》中,Krishnamurthy 等人(2021 年)报道了 SecA 转运蛋白马达中构象动力学的连接点。他们的发现揭示了 Sec 激活机制,并暗示了多层次动力学在蛋白质功能中的普遍作用。
