Gene Rv2440c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Essential GTP-binding protein. |
| Product | Probable GTP1/Obg-family GTP-binding protein Obg |
| Comments | Rv2440c, (MTCY428.06), len: 479 aa. Probable obg, nucleotide-binding protein, equivalent to Q9CBZ4|ML1465 GTP1/OBG-family GTP-binding protein from Mycobacterium leprae (478 aa), FASTA scores: opt: 1328, E(): 8.4e-70, (58.9% identity in 479 aa overlap). Also highly similar to others e.g. P95722|OBG GTP-binding protein from Streptomyces coelicolor (478 aa), FASTA scores: opt: 1311, E(): 8.2e-69, (60.7% identity in 476 aa overlap); P20964|OBG_BACSU SPO0B-associated GTP-binding protein from Bacillus subtilis (428 aa), FASTA scores: opt: 1006, E(): 3.9e-51, (42.9% identity in 436 aa overlap); Q9KDK0|OBG|BH1213 GTP-binding protein involved in initiation of sporulation from Bacillus halodurans (427 aa), FASTA scores: opt: 978, E(): 1.7e-49, (41.95% identity in 436 aa overlap); etc. Highly similar (identical but shorter 5 aa) to AAK46813|MT2516 GTP-binding protein from Mycobacterium tuberculosis strain CDC1551 (484 aa), FASTA scores: opt: 3205, E(): 7.9e-179, (100% identity in 479 aa overlap). Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the GTP1/OBG family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | 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). |
| Transcriptomics | DNA microarrays show higher level of expression in M. tuberculosis H37Rv during Mg2+ starvation (See Walters et al., 2006). |
| 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).
