Gene Rv3853 (menG)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Binds to RNASE E and inhibits RNASE E endonucleolytic cleavages |
| Product | Regulator of RNase E activity a RraA |
| Comments | Rv3853, (MTCY01A6.15c), len: 157 aa. RraA, regulator of RNase E activity A, equivalent to Q9CDD2|RRAA|ML0066 rraA, regulator of RNase E activity a from Mycobacterium leprae (157 aa) FASTA scores: opt: 896, E(): 1.3e-49, (87.1% identity in 155 aa overlap). Also similar to others e.g. P32165|RRAA_ECOLI|B3929|Z5476|ECS4856 from Escherichia coli strain K12 (161 aa), FASTA scores: opt: 428, E(): 3.7e-20, (45.65% identity in 149 aa overlap); etc. Previously known as menG. |
| Functional category | Regulatory proteins |
| Proteomics | Identified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 24h and 96h of starvation (see citation below). |
| 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). Check for mutants available at TARGET website |
