Wie Bakterien die Aufnahme von Kaliumionen regulieren

Abstract

K+ plays an essential role in a different cellular processes in bacteria, and is a central player in microbial adaptation towards a number of environmental challenges. Accordingly, K+ transporters are subject to tight regulation by a diverse set of mechanisms. Here, we discuss three regulatory strategies from three transport systems, as well as the general regulation of K+ homeostasis by the second messenger c-di-AMP.
