General annotation
| Type | CDS |
| Function | Unknown |
| Product | ESX conserved component EccD2. ESX-2 type VII secretion system protein. Probable transmembrane protein. |
| Comments | Rv3887c, (MTCY15F10.25), len: 509 aa. eccD2, esx conserved component, ESX-2 type VII secretion system protein, probable transmembrane protein (has hydrophilic stretch from ~1-130 then very hydrophobic domain), similar to other membrane proteins and with weak similarity to known transporters, e.g. Q9CBV2|ML1539 probable membrane protein from Mycobacterium leprae (503 aa), FASTA scores: opt: 395, E(): 2.3e-16, (28.0% identity in 496 aa overlap); Q9CD35|ML2529 conserved membrane protein from Mycobacterium leprae (485 aa), FASTA scores: opt: 221, E(): 6.6e-06, (24.6% identity in 423 aa overlap); Q9ADP8|2SC10A7.11 putative integral membrane protein from Streptomyces coelicolor (430 aa), FASTA scores: opt: 171, E(): 0.0062, (26.55% identity in 358 aa overlap); CAC44275|SCBAC17F8.03 putative drug efflux protein from Streptomyces coelicolor (416 aa), FASTA scores: opt: 160, E(): 0.028, (27.85% identity in 323 aa overlap); etc. Also similar to others from Mycobacterium tuberculosis e.g. O53944|Rv1795|MTV049.17 putative membrane protein (503 aa), FASTA scores: opt: 360, E(): 2.9e-14, (26.65% identity in 514 aa overlap); etc. Equivalent to AAK48369 from Mycobacterium tuberculosis strain CDC1551 (469 aa) but longer 40 aa. |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). |
| 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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Found to be deleted (partially or completely) in one or more clinical isolates (See Tsolaki et al., 2004). Check for mutants available at TARGET website |
