Linked transport of phosphate, potassium ions and protons in Escherichia coli

The Biochemical Journal
L M Russell, H Rosenberg

Abstract

Pi entry into Escherichia coli cells through either of the two Pi-transport systems (Pit or Pst) prompts the influx of K+ and H+ in a ratio that depends on the external pH. The entry of Pi is absolutely dependent on the presence of K+, and the entry of K+ is equally dependent on the presence of Pi. Experiments with a number of mutants carrying any one functional Pi-transport system and one or more of the individual K+-transport systems indicate a permissive type of linkage of the two transports, in that there is no obvious preference by any of the Pi-transport systems for a particular K+-transport system for the concomitant entry of the two ions.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
