Gene Rv2364c (bex)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Binds both GDP and GTP. Has an intrinsic GTPase activity and is essential for cell growth. |
| Product | Probable GTP-binding protein Era |
| Comments | Rv2364c, (MT2433, MTCY27.16), len: 300 aa. Probable era, GTP-binding protein, equivalent to Q49768|ERA_MYCLE|ML0631|B1937_F3_102 GTP-binding protein era homolog from Mycobacterium leprae (300 aa) FASTA scores: opt: 1589, E(): 3.4e-88, (81.4% identity in 301 aa overlap). Also highly similar to other GTP-binding proteins e.g. Q9RDF2|ERA_STRCO|SCC77.06 from Streptomyces coelicolor (317 aa), FASTA scores: opt: 1264, E(): 1.1e-68, (64.0% identity in 306 aa overlap); Q9KD52|ERA_BACHD|BH1367|BEX from Bacillus halodurans (304 aa), FASTA scores: opt: 869, (44.8% identity in 297 aa overlap); Q9KIH7|ERA_LACLA|ERAL from Lactococcus lactis (subsp. lactis) (Streptococcus lactis), and Lactococcus lactis (subsp. cremoris) (Streptococcus cremoris) (303 aa), FASTA scores: opt: 781, E(): 9.4e-40, (40.25% identity in 298 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the era/TRME family of GTP-binding proteins, era subfamily. Note that previously known as bex. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Translational start site supported by proteomics data (See Kelkar 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). Disruption of this gene results in growth defect of H37Rv in vitro, 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).
