General annotation
TypeCDS
FunctionIt is probably essential for cell survival, being required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation [catalytic activity: ATP + L-methionine + tRNA(met) = AMP + diphosphate + L-methionyl-tRNA(met)]
ProductMethionyl-tRNA synthetase MetS (MetRS) (methionine--tRNA ligase)
CommentsRv1007c, (MTCI237.24), len: 519 aa. metS (MetG), methionyl-tRNA synthetase, similar to many e.g. SYM_BACSU|P37465 methionyl-tRNA synthetase from Bacillus subtilus (664 aa), FASTA scores: opt: 1506, E(): 0, (44.9% identity in 492 aa overlap); similar to other Mycobacterium tuberculosis tRNA synthases e.g. Rv2448c, Rv1536, Rv0041. Contains PS00178 Aminoacyl-transfer RNA synthetases class-I signature. Belongs to class-I aminoacyl-tRNA synthetase family. Strong, to cysteinyl-tRNA synthetase.
Functional categoryInformation pathways
ProteomicsIdentified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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 Kelkar et al., 2011).
MutantEssential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
