Gene Rv0384c (htpM)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Thought to be an ATPase subunit of an intracellular ATP-dependent protease. Seems to be regulated positively by sigh (Rv3223c product) and negatively by HSPR (Rv0353 product). |
| Product | Probable endopeptidase ATP binding protein (chain B) ClpB (ClpB protein) (heat shock protein F84.1) |
| Comments | Rv0384c, (MTV036.19c), len: 848 aa. Probable clpB (alternate gene name: htpM), endopeptidase ATP-binding protein, chain B, equivalent to AC32007.1|AL583925 heat shock protein from Mycobacterium leprae (848 aa). Also highly similar to others e.g. P53532|CLPB_CORGL|1163118|AAB49540.1|U43536|CGU43536_1 CLPB protein (heat-inducible expression) from Corynebacterium glutamicum (852 aa), FASTA scores: opt: 4113, E(): 0, (74.5% identity in 846 aa overlap); T36551|4753885|CAB42048.1|AL049754|clpB|SCOEDB|SCH10.39c probable ATP-dependent proteinase ATP-binding chain from Streptomyces coelicolor (853 aa); P03815|CLPB_ECOLI|1788943|AAC75641.1|AE000345 CLPB protein (heat shock protein F84.1) from Escherichia coli strains K12 and O157:H7 (857 aa); etc. Also similar to Rv3596c|ClpC from Mycobacterium tuberculosis. Contains PS00870 and PS00871 Chaperonins clpA/B signatures and two PS000017 ATP/GTP-binding site motives a (P-loop). Belongs to the CLPA/CLPB family. Contains probable coiled-coil domain from aa 411-503. 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). |

| Proteomics | The product of this CDS corresponds to spots 1_403, 1_404, 1_405 and 1_406 identified in culture supernatant by proteomics at the Max Planck Institute for Infection Biology, Berlin, Germany, and the Statens Serum Institute (Denmark) (see proteomics citations). 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 culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega 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 the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar et al., 2011). |
| Transcriptomics | mRNA identified by DNA microarray analysis and up-regulated at high temperatures (see Stewart et al., 2002). |
| 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 results in growth defect of H37Rv in vitro, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
