Gene Rv0820
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved 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. |
| Product | Probable phosphate-transport ATP-binding protein ABC transporter PhoT |
| Comments | Rv0820, (MTV043.12), len: 258 aa. Probable phoT, phosphate-transport ATP-binding protein ABC transporter (see citation below), equivalent to PhoT|MLU15182_28|U15182 phosphate transport system ABC transporter from Mycobacterium leprae (258 aa), FASTA scores: opt: 1556, E(): 0, (91.5% identity in 258 aa overlap). Also highly similar to others e.g. CAB88472.1|AL353816 phosphate ABC transport system ATP-binding protein from Streptomyces coelicolor (258 aa); etc. Note that also highly similar to many PstB proteins e.g. AAC15686.1|AF045938|PstB putative ABC transporter nucleotide binding subunit from Mycobacterium smegmatis (258 aa). 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). |
| Functional category | Cell wall and cell processes |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene provides a growth advantage 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
