Gene Rv1130
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in methyl citrate cycle |
| Product | Possible methylcitrate dehydratase PrpD |
| Comments | Rv1130, (MTCY22G8.19), len: 526 aa. Possible prpD, methylcitrate dehydratase (MCD), some similarity to AP000063|AP000063_192 hypothetical protein from Aeropyrum pernix (479 aa), FASTA scores: opt: 717, E(): 0, (34.3% identity in 443 a a overlap), and to PRPD_ECOLI|P77243 prpd protein from Escherichia coli (483aa), FASTA scores: opt: 234, E(): 3.3e-08, (27.0% identity in 429 aa overlap). Predicted possible vaccine candidate (See Zvi et al., 2008). |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cytosol of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Detected by 2-DE and MS in M. tuberculosis H37Rv purified from phagosomes of infected murine bone marrow macrophages but not in H37Rv broth-cultures (See Mattow et al., 2006). 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 | mRNA identified by microarray analysis and real-time RT-PCR; transcription up-regulated at low pH in vitro conditions, which may mimic an environmental signal encountered by phagocytosed bacteria (see citation below). DNA microarrays and qRT-PCR show lower level of expression in M. tuberculosis H37Rv than in phoP|Rv0757 mutant (See Walters et al., 2006). |
| 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, but essential for in vitro growth on cholesterol; by sequencing of Himar1-based transposon mutagenesis (See Griffin et al., 2011). M. tuberculosis Erdman prpDC mutant is unable to grow on propionate; growth is severely impaired in non-activated murine bone marrow-derived macrophages and slightly imparied in IFN-gamma-activated macrophages; growth and persistence in the lung and spleen is comparable to wild-type (See Munoz-Elias et al., 2006). M. tuberculosis H37Rv prpDC mutant is unable to grow on propionate or valerate, but can grow when supplemented with vitamin B12 and 3-nitropropionate has no effect on this growth; prpDC mutant can grow on heptodecanoate and growth is improved when supplemented with vitamin B12; prpDC-mutAB mutant is unable to grow on B12-supplemented propionate (See Savvi et al., 2008).
