ProductAntitoxin RelB
CommentsRv1247c, (MTV006.19c), len: 89 aa. RelB, antitoxin, part of toxin-antitoxin (TA) operon with Rv1246c (See Pandey and Gerdes, 2005), some similarity to hypothetical proteins including Mycobacterium tuberculosis proteins Rv2865|MTV003.11 (93 aa), FASTA scores: opt: 249, E(): 5.4e-13, (44.2% identity in 86 aa overlap); Rv0268|Z86089|P95225 (169 aa) opt: 125, E(): 0.0089, (41.8% identity in 55 aa overlap); etc. and Escherichia coli AE000293|ECAE0002933 (92 aa), FASTA scores: opt: 127, E(): 0.0038, (29.3% identity in 82 aa overlap).
Functional categoryVirulence, detoxification, adaptation
ProteomicsIdentified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen 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 de Souza et al., 2011) (See Kelkar et al., 2011).
OperonRv1247c and Rv1246c are co-transcribed, by RT-PCR (See Korch et al., 2009).
MutantNon-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).
