FunctionInvolved in active transport of inorganic phosphate across the membrane (import); responsible for energy coupling to the transport system. This is one of the proteins required for binding-protein-mediated phosphate transport. Have ATP-binding ability and ATPase activity.
ProductPhosphate-transport ATP-binding protein ABC transporter PstB
CommentsRv0933, (MTCY08D9.06c), len: 276 aa. PstB, phosphate-transport ATP-binding protein ABC transporter (see citations below), thermostable ATPase, highly similar to others e.g. NP_348334.1|NC_003030 ATPase component of ABC-type phosphate transport system from Clostridium acetobutylicum (249 aa); NP_212352.1|NC_001318 phosphate ABC transporter ATP-binding protein (pstB) from Borrelia burgdorferi (260 aa); NP_390375.1|NC_000964 phosphate ABC transporter (ATP-binding protein) from Bacillus subtilis (269 aa), FASTA scores: opt: 762, E(): 0, (47.7% identity in 243 aa overlap); etc. Also similar to other M. tuberculosis ABC transporters e.g. MTCY253.24, E(): 2.5e-15 and MTCY359.14c, E(): 3.4e-15. Contains PS00211 ABC transporters family signature, and PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the ATP-binding transport protein family (ABC transporters). Magnesium or calcium seem to have no influence on the functionality of this enzyme.

ProteomicsIdentified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cell membrane fraction 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 by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantNon-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003).
