Gene Rv2555c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in translation mechanism [catalytic activity: ATP + L-alanine + tRNA(ala) = AMP + pyrophosphate + L-alanyl-tRNA (ala)]. |
| Product | Probable alanyl-tRNA synthetase AlaS (alanine--tRNA ligase) (alanine translase) (ALARS) |
| Comments | Rv2555c, (MTCY318.01c-MTCY159.01), len: 904 aa. Probable alaS, alanyl-tRNA synthetase, equivalent to Q9CCT0|alas|ML0512 alanyl-tRNA synthetase from Mycobacterium leprae (908 aa), FASTA scores: opt: 5013, E(): 0, (84.65% identity in 907 aa overlap). Also highly similar to many e.g. Q9KXP9|alas from Streptomyces coelicolor (890 aa), FASTA scores: opt: 2159, E(): 3.8e-118, (53.45% identity in 907 aa overlap); Q9FFC7 Arabidopsis thaliana (Mouse-ear cress) (954 aa), FASTA scores: opt: 1963, E(): 1.1e-106, (41.1% identity in 925 aa overlap); Q9RS27|DR2300 from Deinococcus radiodurans (890 aa), FASTA scores: opt: 1352, E(): 4.1e-71, (38.05% identity in 915 aa overlap); etc. Belongs to class-II aminoacyl-tRNA synthetase family. |

| Proteomics | Identified by proteomics at the Statens Serum Institute (Denmark) (See Rosenkrands et al., 2000). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). 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 | Essential 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).
