in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown |
| Product | ESX conserved component EccE1. ESX-1 type VII secretion system protein. Possible membrane protein. |
| Comments | Rv3882c, (MTV027.17c, MTCY15F10.30), len: 462 aa. eccE1, esx conserved component, ESX-1 type VII secretion system protein, possible membrane protein, equivalent to O33077|ML0042|MLCB628.05 putative membrane protein from Mycobacterium leprae (467 aa), FASTA scores: opt: 2346, E(): 1.1e-140, (72.1% identity in 462 aa overlap). Also similar to O05459|Rv3885c|MTCY15F10.27 possible membrane protein from Mycobacterium tuberculosis (537 aa) FASTA scores: opt: 283, E(): 2.5e-10, (26.8% identity in 414 aa overlap); and C-terminal end shows similarity with AAK48368|MT4000 hypothetical 45.6 KDA protein from Mycobacterium tuberculosis strain CDC1551 (422 aa) FASTA scores: opt: 215, E(): 4.1e-06, (26.85% identity in 320 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). Rv3614c and Rv3882c interact, by yeast two-hybrid analysis (See MacGurn et al., 2005). |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar 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). Disruption of this gene provides a growth advantage 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 |
