General annotation
FunctionInvolved in active transport of inorganic phosphate across the membrane (import); responsible for the translocation of the substrate across the membrane. This is one of the proteins required for binding-protein-mediated phosphate transport.
ProductPhosphate-transport integral membrane ABC transporter PstA2
CommentsRv0936, (MTCY08D9.03c), len: 301 aa. PstA2, phosphate-transport integral membrane ABC transporter (see citations below), highly similar to others e.g. NP_442269.1|NC_000911|PstA phosphate transport system permease protein from Synechocystis sp. strain PCC 6803 (287 aa); NP_232473.1|NC_002506 phosphate ABC transporter permease protein from Vibrio cholerae (289 aa); P07654|PSTA_ECOLI phosphate transport system permease from Escherichia coli (296 aa), FASTA scores: opt: 464, E(): 6.7e-24, (30.5% identity in 282 aa overlap); etc. Also similar to O86345|MTCY21C12.24|PSTA1|Rv0930 probable transmembrane ABC transporter component of phosphate uptake system from Mycobacterium tuberculosis (304 aa), FASTA scores: opt: 369, E(): 6.1e-15, (32.7% identity in 248 aa overlap). Contains binding-protein-dependent transport systems inner membrane comp signature (PS00402).
Functional categoryCell wall and cell processes
ProteomicsIdentified 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, 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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
