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:2197272, ECO:0000269|PubMed:3038843,
CC ECO:0000269|PubMed:3283129, ECO:0000269|PubMed:3522583,
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,
