Gene Rv1398c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Unknown |
| Product | Possible antitoxin VapB10 |
| Comments | Rv1398c, (MTCY21B4.15c), len: 85 aa. Possible vapB10, antitoxin, part of toxin-antitoxin (TA) operon with Rv1397c (See Arcus et al., 2005; Pandey and Gerdes, 2005). Similar to others in Mycobacterium tuberculosis e.g. Rv2547|MTCY159.09C (85 aa), FASTA scores: E(): 0.0035, (37.1% identity in 62 aa overlap); Rv0581, Rv2871, Rv1241, etc. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007). |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). 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 microarray analysis and up-regulated after 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 for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
