Gene Rv3232c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Catalyzes the reversible transfer of phosphate from polyphosphate (polyp) to form GTP [catalytic activity: GDP + {phosphate}(N) = GTP + {phosphate}(N-1)]. |
| Product | Polyphosphate kinase Ppk2 (polyphosphoric acid kinase) |
| Comments | Rv3232c, (MTCY20B11.07c), len: 295 aa (start uncertain). Ppk2, polyphosphate kinase 2, highly similar to Q9I154|PA2428 hypothetical protein from Pseudomonas aeruginosa (304 aa), FASTA scores: opt: 1057, E(): 6.8e-62, (60.7% identity in 252 aa overlap); Q9I6Z1|PA0141 hypothetical protein from Pseudomonas aeruginosa (298 aa), FASTA scores: opt: 990, E(): 1.6e-57, (54.6% identity in 249 aa overlap); and other hypothetical bacterial proteins. Note that previously known as pvdS. Ppk2|Rv3232c and NdkA|Rv2445c interact (See Sureka et al., 2009). |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Mutant | Non-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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Non essential gene for growth in vitro by Tn5370 transposon mutagenesis of H37Rv strain but mutant is less virulent in SCID mice (see McAdam et al., 2002).
