RESUMO
Disruption of pstS encoding the Pi-binding protein in Escherichia coli generally leads to the constitutive expression of the pho regulon. We demonstrate that Pi-controlled expression is restored when the activity of the Pi transporter PitA or PitB is increased. Apparently, PstS is not an essential component of the signal transduction pathway.
