in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown |
| Product | Possible toxin VapC23 |
| Comments | Rv2863, (MTV003.09), len: 126 aa. Possible vapC23, toxin, part of toxin-antitoxin (TA) operon with Rv2862A, contains PIN domain (See Arcus et al., 2005; Pandey and Gerdes, 2005). Similar to others in Mycobacterium tuberculosis e.g. Q50595|YI38_MYCTU|Rv1838c|MT1886|MTCY1A11.05|MTCY359.35 conserved hypothetical protein (131 aa), FASTA scores: opt: 299, E(): 6.5e-15, (39.0% identity in 123 aa overlap). |
| Functional category | Virulence, detoxification, adaptation |
| 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). 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 |
