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