FunctionInvolved in translation mechanisms [catalytic activity: ATP + L-glutamate + tRNA(GLU) = AMP + diphosphate + L-glutamyl-tRNA(GLU)].
ProductGlutamyl-tRNA synthetase GltS (glutamate--tRNA ligase) (glutamyl-tRNA synthase) (GLURS)
CommentsRv2992c, (MTV012.06c), len: 490 aa. GltS (alternate gene name: gltX), glutamyl-tRNA synthase, equivalent to O33120|SYE_MYCLE glutamyl-tRNA synthetase from Mycobacterium leprae (502 aa), FASTA scores: opt: 2660, E(): 2.3e-163, (81.35% identity in 488 aa overlap). Also highly similar to others e.g. O86528|SYE_STRCO from Streptomyces coelicolor (494 aa), FASTA scores: opt: 1777, E(): 1.4e-106, (57.45% identity in 484 aa overlap); P22250|SYE_BACSU from Bacillus subtilis (483 aa), FASTA scores: opt: 1099, E(): 5.4e-63, (38.45% identity in 489 aa overlap); O51345|SYE_BORBU|GLTX|BB0372 from Borrelia burgdorferi (Lyme disease spirochete) (490 aa), FASTA scores: opt: 1009, E(): 3.3e-57, (34.85% identity in 491 aa overlap); etc. Belongs to class-I aminoacyl-tRNA synthetase family.
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).
TranscriptomicsmRNA identified by microarray analysis and down-regulated after 96h of starvation (see citation below).
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).
