in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown |
| Product | PPE family protein PPE68 |
| Comments | Rv3873, (MTV027.08), len: 368 aa. PPE68, Member of the Mycobacterium tuberculosis PPE family, highly similar to many e.g. O33085|ML0051|MLCB628.14c from Mycobacterium leprae (302 aa), FASTA scores: opt: 656, E(): 2.8e-24, (46.2% identity in 288 aa overlap); and O53691|Rv0286|MTV035.14 (513 aa), FASTA scores: opt: 566, E(): 7.8e-20, (35.25% identity in 363 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). Predicted possible vaccine candidate (See Zvi et al., 2008). |
| Functional category | Pe/ppe |
| Proteomics | 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). |
| Transcriptomics | mRNA identified by RT-PCR (See Amoudy et al., 2006). |
| Mutant | Non-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 CDC1551 strain (see Lamichhane et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Survival of SCID mice infected with M. tuberculosis H37Rv Rv3872-Rv3873 mutant is comparable to those infected with wild-type; Rv3875 protein detected by Western blot in culture filtrate of mutant (See Hsu et al., 2003).
