in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Sequence-specific mRNA cleavage |
| Product | Toxin MazF9 |
| Comments | Rv2801c, (MTCY16B7.42), len: 118 aa. MazF9, toxin, part of toxin-antitoxin (TA) operon with Rv2801A (See Pandey and Gerdes, 2005; Zhu et al., 2006), highly similar to Q9RWK4|DR0662 conserved hypothetical protein from Deinococcus radiodurans (115 aa), FASTA scores: opt: 306, E(): 2e-15, (43.95% identity in 116 aa overlap); and similar to AAK78474|CAC0494 PEMK family of DNA-binding proteins from Clostridium acetobutylicum (122 aa), FASTA scores: opt: 217, E(): 7.3e-09, (33.35% identity in 117 aa overlap); P96622|YDCE YDCE protein from Bacillus subtilis (116 aa), FASTA scores: opt: 194, E(): 3.5e-07, (33.35% identity in 117 aa overlap); Q9PHH8|XFA0027 plasmid maintenance protein from Xylella fastidiosa (108 aa), FASTA scores: opt: 188, E(): 9.1e-07, (40.85% identity in 115 aa overlap); etc. Also similar to Q10867|YJ91_MYCTU|Rv1991c|MT2046|MTCY39.28 hypothetical 12.3 KDA protein from Mycobacterium tuberculosis (114 aa), FASTA scores: opt: 190, E(): 6.8e-07, (36.75% identity in 117 aa overlap). This region is a possible MT-complex-specific genomic island (See Becq et al., 2007). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza 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 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 |
