Gene Rv3379c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Catalyzes the acyloin condensation reaction between C atoms 2 and 3 of pyruvate and glyceraldehyde 3-phosphate to yield 1-deoxy-D-xylulose-5-phosphate (DXP). Possibly involved in deoxyxylulose-5-phosphate pathway (DXP) of isoprenoid biosynthesis (at the first step), and biosynthetic pathway to thiamine andpyridoxol (at the first step). |
| Product | Probable 1-deoxy-D-xylulose 5-phosphate synthase Dxs2 (1-deoxyxylulose-5-phosphate synthase) (DXP synthase) (DXPS) |
| Comments | Rv3379c, (MTV004.37c), len: 536 aa. Probable dxs2, 1-deoxy-D-xylulose 5-phosphate synthase, similar to many e.g. Q9F1V2|DXS from Kitasatospora griseola (Streptomyces griseolosporeus) (649 aa), FASTA scores: opt: 1274, E(): 5.4e-71, (50.9% identity in 570 aa overlap); Q9X7W3|DXS_STRCO|SC6A5.17 from Streptomyces coelicolor (656 aa), FASTA scores: opt: 1248, E(): 2.2e-69, (50.55% identity in 568 aa overlap); Q9RBN6|DXS_STRC1 from Streptomyces sp. strain CL190 (631 aa), FASTA scores: opt: 1237, E(): 1e-68, (49.1% identity in 570 aa overlap); Q50000|DXS_MYCLE|TKTB|ML1038 from Mycobacterium leprae (643 aa), FASTA scores: opt: 1215, E(): 2.4e-67, (46.75% identity in 571 aa overlap); Q9R6S7|DXS_SYNLE from Synechococcus leopoliensis (636 aa), FASTA scores: opt: 849, E(): 8.9e-45, (38.55% identity in 550 aa overlap); etc. Also similar to O07184|DXS_MYCTU|Rv2682c|MT2756|MTCY05A6.03c from Mycobacterium tuberculosis (638 aa), FASTA scores: opt: 1226, E(): 4.9e-68, (48.9% identity in 558 aa overlap). Belongs to the transketolase family, DXS subfamily. Cofactor: thiamine pyrophosphate (by similarity). Note that the N-terminus of this putative protein appears to have been interrupted by the adjacent IS6110 element. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| 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, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
