Résumé:
The membrane-associated phosphate-specific transporter (Pst) complex is composed of four different proteins: PstS, PstC, PstA and PstB. The PstS component detects and binds Pi with high affinity; the PstA and PstC form transmembrane pores for Pi entry, while PstB provides energy through ATP hydrolysis. In the Mycobacterium tuberculosis genome, four different gene clusters encode three PstS, and two of each of the other sub-units. We used RT-PCR to show that these clusters represent at least three distinct operons. The pstS3-containing operon was the only one induced by lack of environmental…
