RESUMO
Two systems for the uptake of inorganic phosphate (Pi) in Escherichia coli, PitA and Pst, have been described. A revertant of a pitA pstS double mutant that could grow on Pi was isolated. We demonstrate that the expression of a new Pi transporter, PitB, is activated in this strain by a gene amplification event.
