Term Name:	high-affinity phosphate:sodium symporter activity
Synonyms:	high affinity inorganic phosphate:sodium symporter activity, high-affinity inorganic phosphate:sodium symporter activity, sodium/phosphate cotransporter activity
Definition:	Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction:phosphate(out) + Na+(out) = phosphate(in) + Na+(in). In high-affinity transport the transporter is able to bind the solute even if it is only present at very low concentrations.
