| Comments | Rv3869, (MTV027.04), len: 480 aa. EccB1, esx conserved component, ESX-1 type VII secretion system protein, possible membrane protein (has hydrophobic stretch near N-terminus), equivalent to O33088|ML0054|MLCB628.17c putative membrane protein from Mycobacterium leprae (481 aa), FASTA scores: opt: 2489, E(): 8.3e-136, (75.75% identity in 478 aa overlap); and similar to others e.g. Q9Z5I3|ML1544|MLCB596.27 conserved membrane protein from Mycobacterium leprae (506 aa), FASTA scores: opt: 739, E(): 3.9e-35, (33.65% identity in 490 aa overlap). Also similar to hypothetical proteins from Mycobacterium tuberculosis e.g. O05449|Rv3895c|MTCY15F10.17 (495 aa), FASTA scores: opt: 795, E(): 2.3e-38, (35.8% identity in 486 aa overlap); O53933|Rv1782|MTV049.04 (506 aa), FASTA scores: opt: 763, E(): 1.6e-36, (34.7% identity in 490 aa overlap); O06317|Rv3450c|MTCY13E12.03c (470 aa) FASTA scores: opt: 717, E(): 6.7e-34, (32.55% identity in 479 aa overlap); etc. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). |

| Proteomics | Identified in the detergent phase of Triton X-114 extracts of M. tuberculosis H37Rv membranes using 1-DGE and MALDI-TOF-MS (See Sinha 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 30 days but not 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 4h of starvation (see transcriptome citation). |
| 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 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). Check for mutants available at TARGET website |
