'''Phosphate-binding protein''' (PBP) binds phosphate (Pi) with high affinity. PBP is involved in various biological processes like cell cycle regulation. PBP is produced under conditions of low Pi concentration. It binds Pi in the periplasm and transfers it to a membrane protein which transports it to the cytoplasm. PBP undergoes conformational change upon binding to Pi<ref>PMID:25338617</ref>. | '''Phosphate-binding protein''' (PBP) binds phosphate (Pi) with high affinity.
