in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |

| Product | ESX conserved component EccC4. ESX-4 type VII secretion system protein. Probable membrane protein. |
| Comments | Rv3447c, (MTCY77.19c), len: 1236 aa. EccC4, esx conserved component, ESX-4 type VII secretion system protein, probable membrane protein, similar to various bacterial proteins e.g. O86653|SC3C3.20c ATP/GTP binding protein from Streptomyces coelicolor (1321 aa), FASTA scores: opt: 1186, E(): 1.9e-60, (42.9% identity in 1312 aa overlap); Q9L0T6|SCD35.15c from Streptomyces coelicolor (1525 aa), FASTA scores: opt: 932, E(): 9.2e-46, (27.2% identity in 1374 aa overlap); Q9CD30|ML2535 hypothetical protein from Mycobacterium leprae (1329 aa), FASTA scores: opt: 910, E(): 1.5e-44, (34.4% identity in 1319 aa overlap); Q9KE81|BH0975 hypothetical protein from Bacillus halodurans (1489 aa), FASTA scores: opt: 805, E(): 1.9e-38, (25.85% identity in 1292 aa overlap); etc. The C-terminal region is similar to Q9CDD7|ML0052 (alias O33086|MLCB628.15c) hypothetical protein from Mycobacterium leprae (597 aa), FASTA scores: opt: 850, E(): 2.3e-41, (35.2% identity in 588 aa overlap); and O6973|Rv3871|MTV027.06 hypothetical protein from Mycobacterium tuberculosis (591 aa), FASTA scores: opt: 845, E(): 4.3e-41, (35.3% identity in 586 aa overlap). N-terminal part shows similarity with hypothetical proteins from Mycobacterium tuberculosis e.g. O69735|Rv3870|MTV027.05 (747 aa), FASTA scores: opt: 761, E(): 3.6e-36, (38.2% identity in 746 aa overlap). Equivalent to AAK47893 from Mycobacterium tuberculosis strain CDC1551 (1200 aa) but longer 36 aa. Contains three of PS00017 ATP/GTP-binding site motif A (P-loop). |
| 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 30 and 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 CDC1551 strain (see Lamichhane et al., 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 |
