Gene Rv2404c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in translation. |
| Product | Probable GTP-binding protein LepA (GTP-binding elongation factor) |
| Comments | Rv2404c, (MT2476, MTCY253.16), len: 653 aa. Probable lepA, GTP-binding protein (a protein of unknown function, but apparently with membrane-related functions and very similar to protein synthesis elongation factors; see citations below). Equivalent to P53530|LEPA_MYCLE|ML0611|B1937_F3_81 GTP-binding protein from Mycobacterium leprae (646 aa), FASTA scores: opt: 3610, E(): 1.2e-205, (88.0% identity in 649 aa overlap). Also highly similar to many GTP-binding proteins LEPA e.g. Q9RDC9|LEPA_STRCO|SCC77.29c from Streptomyces coelicolor (622 aa), FASTA scores: opt: 3046, E(): 2.3e-172, (74.3% identity in 626 aa overlap); P37949|LEPA_BACSU from B. subtilis (612 aa), FASTA scores: opt: 2430, E(): 5.3e-136, (58.7% identity in 610 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop), and PS00301 GTP-binding elongation factors signature. Belongs to the GTP-binding elongation factor family, LEPA subfamily. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cytosol and cell wall fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega 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 | 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). 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 |
