Gene Rv0724
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in digestion of the cleaved signal peptides. This activity is necessary to maintain proper secretion of mature proteins across the membrane. |
| Product | Possible protease IV SppA (endopeptidase IV) (signal peptide peptidase) |
| Comments | Rv0724, (MTCY210.43), len: 623 aa. Possible sppA, protease IV (endopeptidase IV), equivalent (but longer 23 aa) to MLCB2492_24|O33003 endopeptidase IV from Mycobacterium leprae (602 aa). Also similar to others e.g. NP_419743.1|NC_002696 signal peptide peptidase SppA from Caulobacter crescentus (594 aa); P08395|SPPA_ECOLI|B1766 protease IV (endopeptidase) from Escherichia coli strain K-12 (618 aa), FASTA scores: opt: 582, E(): 8.9e-27, (34.1% identity in 525 aa overlap); etc. Belongs to peptidase family S49. Conserved in M. tuberculosis, M. leprae, M. bovis and M. avium paratuberculosis; predicted to be essential for in vivo survival and pathogenicity (See Ribeiro-Guimaraes and Pessolani, 2007). |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified by proteomics (See Rosenkrands et al., 2000). Identified 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 M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the membrane protein fraction 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). 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). 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 |
