9.B.20.1.1
Putative Mg2+ transporter, MgtC (Retamal et al. 2009). The MgtC virulence protein binds to the F-type ATP synthase and maintains ATP homeostasis required for pathogenesis during phagosome acidification (Lee and Lee 2015). The mgtC gene, which is present in S. enterica but not in E. coli, is responsible for the differences in RpoS accumulation between these two bacterial species. Thus, bacteria possess a mechanism to control RpoS accumulation responding to cytoplasmic Mg2+ levels, the difference of which causes distinct RpoS accumulation patterns in closely related bacterial species (Park et al. 2018).
