General annotation
TypeCDS
FunctionInvolved in active transport of inorganic phosphate across the membrane (import). This is one of the proteins required for binding-protein-mediated phosphate transport.
ProductPeriplasmic phosphate-binding lipoprotein PstS1 (PBP-1) (PstS1)
CommentsRv0934, (MTCY08D9.05c), len: 374 aa. PstS1 (previously known as phoS1 or phoS), phosphate-binding lipoprotein component of inorganic phosphate transport system (see citations below), highly similar to Rv0932c|MTCY08D9.07|pstS2 phosphate-binding periplasmic lipoprotein from Mycobacterium tuberculosis (370 aa), FASTA scores: opt: 460, E(): 5.9e-19, (31.2% identity in 375 aa overlap); and Rv0928|MTCY21C12.22|pstS3 phosphate-binding periplasmic lipoprotein from Mycobacterium tuberculosis (374 aa), FASTA scores: opt: 435, E():1.1e-17, (30.0% identity in 380 aa overlap) (Mycobacterium tuberculosis seems to have three PstS-like proteins, others being Rv0932c and Rv0928c). Also highly similar to MTCY08D9.05c|P15712|PAB_MYCTU protein antigen B precursor from Mycobacterium tuberculosis (374 aa), FASTA scores: opt: 2459, E(): 0, (100% identity in 374 aa overlap). Contains a prokaryotic membrane lipoprotein lipid attachment site (PS00013) at the N-terminus so the 23 aa leader peptide sequence is probably removed. Belongs to family of phosphate receptors for bacterial ABC-type lipoprotein transporters.

ProteomicsThe product of this CDS corresponds to spot 0934 identified in short term culture filtrate by proteomics at the Statens Serum Institute (Denmark) (see proteomics citations). Identified in immunodominant fractions of M. tuberculosis H37Rv culture filtrate using 2D-LPE, 2D-PAGE, and LC-MS or LC-MS/MS (See Covert et al., 2001). Identified in Triton X-114 extracts of M. tuberculosis H37Rv membranes using 2DGE and MALDI-MS (See Sinha et al., 2002). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry and Edman degradation (See Mattow et al., 2003). Identified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). Identified in the detergent phase of Triton X-114 extracts of M. tuberculosis H37Rv membranes using 1-DGE and MALDI-TOF-MS (See Sinha et al., 2005). Predicted surface lipoprotein - identified in culture filtrates of M. tuberculosis H37Rv; signal peptide predicted (See Malen et al., 2007). Identified in the culture filtrate of M. tuberculosis H37Rv using LC-MS/MS; antigen recognized by serum pool from tuberculosis patients (See Malen et al., 2008). Putative glycoprotein identified by LC/ESI-MS/MS in the culture filtrate of M. tuberculosis H37Rv (See Gonzalez-Zamorano et al., 2009). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011).
