运动的大肠杆菌细胞用跨膜化学感受器蛋白跟踪环境中引诱剂和驱避剂化学物质的梯度。这些受体在合作阵列中操作,以响应于化学效应物浓度的微小变化而产生信号激酶CheA活性的大变化。最近的研究提供了更深入的了解的结构和功能的核心受体信号复合物和高阶受体阵列的架构,这反过来又导致了新的见解的分子信号机制的化学受体网络。目前的证据支持一种新的观点,受体信号刺激信息在受体分子内通过相邻结构元件的动态特性的变化,而不是通过一些离散的构象状态。
Motile Escherichia coli cells track gradients of attractant and repellent chemicals in their environment with transmembrane chemoreceptor proteins. These receptors operate in cooperative arrays to produce large changes in the activity of a signaling kinase CheA in response to small changes in chemoeffector concentration. Recent research has provided much deeper understanding of the structure and function of core receptor signaling complexes and the architecture of higher-order receptor arrays, which in turn has led to new insights into the molecular signaling mechanisms of chemoreceptor networks. Current evidence supports a new view of receptor signaling in which stimulus information travels within receptor molecules through shifts in the dynamic properties of adjoining structural elements rather than through a few discrete conformational states.
