| Product | Conserved transmembrane transport protein MmpL7 |
| Comments | Rv2942, (MTCY24G1.07c), len: 920 aa. MmpL7, conserved transmembrane transport protein (see citations below), member of RND superfamily, highly similar to Q9XB10 hypothetical 99.5 KDA protein from Mycobacterium bovis BCG (945 aa), FASTA scores: opt: 488, E(): 4.9e-20, (29.5% identity in 918 aa overlap); and to others from Mycobacteria e.g. O53735|MML4_MYCTU from Mycobacterium tuberculosis (945 aa), FASTA scores: opt: 481, E(): 1.2e-19, (25.9% identity in 922 aa overlap); etc. Also similar to other membrane proteins e.g. O54101|MMLB_STRCO|SC10A5.10c putative membrane protein from Streptomyces coelicolor (847 aa), FASTA scores: opt: 256, E(): 7.2e-07, (25.15% identity in 545 aa overlap); etc. Contains PS00639 Eukaryotic thiol (cysteine) proteases histidine active site, PS00079 Multicopper oxidases signature 1, and PS00044 Bacterial regulatory proteins, lysR family signature. Belongs to the MmpL family. Note that Rv2941|fadD28 and Rv2942|mmpL7 are transcriptionally coupled (proven experimentally). |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS; predicted integral membrane protein (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 and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 24h of starvation (see Betts et al., 2002). |
| 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 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 |
