| Type | CDS |
| Function | Function unknown |
| Product | ESX conserved component EccA5. ESX-5 type VII secretion system protein. |
| Comments | Rv1798, (MTV049.20), len: 610 aa. eccA5, esx conserved component, ESX-5 type VII secretion system protein, similar to several mycobacterial proteins e.g. O05460|MTCY15F10.28|Rv3884c|Z94121 from M. tuberculosis (619 aa), FASTA scores: opt: 669, E(): 0, (31.0% identity in 549 aa overlap); and O33089|MLCB628.18c|Y14967 from Mycobacterium leprae (573 aa), FASTA scores: opt: 723, E(): 0, (32.4% identity in 568 aa overlap). Also very similar to Rv0282. May belong to the CbxX/CfqX family as last ~320 aa domain very similar to several family members. Contains ATP/GTP-binding site motif A (P-loop; PS00017). |
| 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 M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). 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). 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). Essential gene for in vitro growth of H37Rv on cholesterol, by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
