CC   -!- FUNCTION: Mediates the exchange of external hexose 6-phosphate and
CC       internal inorganic phosphate. Can transport glucose-6-phosphate,
CC       fructose-6-phosphate and mannose-6-phosphate. Also catalyzes the
CC       neutral exchange of internal and external phosphate.

CC       ECO:0000269|PubMed:5330662, ECO:0000269|PubMed:8402899}.
CC   -!- ACTIVITY REGULATION: Reaction is unaffected by the ionophores
CC       valinomycin, valinomycin plus nigericin, and carbonyl cyanide p-
CC       trifluoromethoxyphenylhydrazone (FCCP). {ECO:0000269|PubMed:3283129}.
CC   -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:2197272}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000269|PubMed:15919996,

CC       membrane protein {ECO:0000255, ECO:0000269|PubMed:2156798}.
CC   -!- INDUCTION: Expression is induced by external glucose-6-phosphate
CC       through the UhpABC signaling cascade. {ECO:0000269|PubMed:11739766,
CC       ECO:0000269|PubMed:3038843, ECO:0000269|PubMed:4905309,
