Abstract
Escherichia coli chemoreceptors can sense changes in temperature for thermotaxis. Here we found that the aerotaxis transducer Aer, a homolog of chemoreceptors lacking a periplasmic domain, mediates thermoresponses. We propose that thermosensing by the chemoreceptors is a general attribute of their highly conserved cytoplasmic domain (or their less conserved transmembrane domain).
摘要
大肠杆菌化学感受器可以感知温度变化以进行趋温性。在这里，我们发现，趋气性转导蛋白 Aer（一种缺乏周质域的化学感受器同源物）介导了热响应。我们提出，化学感受器的热感应是其高度保守的细胞质域（或其不太保守的跨膜域）的普遍属性。
