Gene Rv3407
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown |
| Product | Possible antitoxin VapB47 |
| Comments | Rv3407, (MTCY78.21c), len: 99 aa. Possible vapB47, antitoxin, part of toxin-antitoxin (TA) operon with Rv3408, see Arcus et al. 2005. Similar to others in Mycobacterium tuberculosis strains H37Rv and CDC1551 e.g. AAK46285|MT2013 (90 aa), FASTA scores: opt: 160, E(): 0.00021, (37.1% identity in 89 aa overlap); O50412|Rv3385c|MTV004.43c (102 aa), FASTA scores: opt: 155, E(): 0.00051, (41.05% identity in 78 aa overlap), MTCY19H5.26, MTCY20H10.07, MTI376.09c, MTCY427.21, etc. |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | The product of this CDS corresponds to spot 6_52 identified by proteomics at the Max Planck Institute for Infection Biology, Berlin, Germany (see Mattow et al., 2001). 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). |
| Transcriptomics | mRNA identified by DNA microarray analysis and possibly down-regulated by hspR|Rv0353 (see Stewart et al., 2002). |
| Mutant | 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). 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 |
