Gene Rv2870c (ispC)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in the deoxyxylulose-5-phosphate pathway (DXP) of isoprenoid biosynthesis (at the second step). Catalyzes the NADP-dependent rearrangement and reduction of 1-deoxy-D-xylulose-5-phosphate (DXP) to 2-C-methyl-D- erythritol 4-phosphate (MEP). |
| Product | Probable 1-deoxy-D-xylulose 5-phosphate reductoisomerase Dxr (DXP reductoisomerase) (1-deoxyxylulose-5-phosphate reductoisomerase) |
| Comments | Rv2870c, (MTCY274.01c, MTV003.16c), len: 413 aa. Probable dxr, 1-deoxy-D-xylulose 5-phosphate reductoisomerase, equivalent to Q9CBU3|DXR|ML1583 1-deoxy-D-xylulose 5-phosphate reductoisomerase from Mycobacterium leprae (406 aa), FASTA scores: opt: 2145, E(): 1e-124, (84.05% identity in 395 aa overlap). Also highly similar to others e.g. Q9AJD7|DXR from Kitasatospora griseola (Streptomyces griseolosporeus) (386 aa), FASTA scores: opt: 1176, E(): 5.2e-65, (56.45% identity in 388 aa overlap); Q9KYS1|DXR_STRCO|SC5H4.18 from Streptomyces coelicolor (401 aa), FASTA scores: opt: 1079, E(): 5.1e-59, (52.25% identity in 396 aa overlap); P45568|DXR|B0173 from Escherichia coli strain K12 (398 aa), FASTA scores: opt: 120, E(): 0.032, (52.9% identity in 34 aa overlap); etc. Contains PS00133 Zinc carboxypeptidases, zinc-binding region 2 signature. Belongs to the DXR family. N-terminus shortened since first submission. |
| 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). |
| 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). Non 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). Check for mutants available at TARGET website |
