Gene Rv1640c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Charging LYS tRNA [catalytic activity: ATP + L-lysine + tRNA(LYS) = AMP + diphosphate + L-lysyl-tRNA (LYS)] |
| Product | Lysyl-tRNA synthetase 2 LysX |
| Comments | Rv1640c, (MTCY06H11.04c), len: 1172 aa. lysX, lysyl-tRNA synthetase 2, probable two domain protein. N-terminal part (bases 1850153 to 1852033) is similar to AL023861|SC3C8_3 hypothetical membrane protein from Streptomyces coelicolor (589 aa), Fasta scores: opt: 1426, E(): 0, (44.6% identity in 585 aa overlap). The C-terminal part is similar to SYK_CRILO|P37879 lysyl-tRNA synthetases from Cricetulus longicaudatus (Long-tailed hamster) (597 aa), Fasta scores, opt: 985, E(): 0, (36.8% identity in 524 aa overlap). Contains PS00179 Aminoacyl-transfer RNA synthetases class-II signature 1, PS00339 Aminoacyl-transfer RNA synthetases class-II signature 2. This may indicate a frame shift but sequence has been checked and no error found. Belongs to class-II aminoacyl-tRNA synthetase family. |
| Functional category | Information pathways |
| Proteomics | Identified in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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). |
| 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). Essentialgene by Himar1 transposon mutagenesis in CDC1551 strain (see Lamichhane et al., 2003). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). M. tuberculosis H37Rv transposon mutant is sensitive to pH 4.5 in 7H9 with Tween or Tyloxapol, but not phosphate-citrate buffer with Tyloxapol; mutant is not attenuated in C57BL/6 mice (See Vandal et al., 2008).
