Expressioni
Inductioni
Transcription induced by phosphate starvation, no change in protein levels on phosphate starvation (at protein level). If bacteria are starved prior to growth in phosphate-free medium protein expression disappears.1 Publication
Interactioni
Subunit structurei
The complex is composed of two ATP-binding proteins (PstB), two transmembrane proteins (PstC and PstA) and a solute-binding protein (PstS).
