Gene Rv3318
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in tricarboxylic acid cycle. Membrane-bound FAD-containing enzyme which is responsible for succinate interconversion [catalytic activity: succinate + acceptor = fumarate + reduced acceptor]. |
| Product | Probable succinate dehydrogenase (flavoprotein subunit) SdhA (succinic dehydrogenase) (fumarate reductase) (fumarate dehydrogenase) (fumaric hydrogenase) |
| Comments | Rv3318, (MTV016.18), len: 590 aa. Probable sdhA, flavoprotein of succinate dehydrogenase SdhA subunit, equivalent to Q9CCM1|SDHA|ML0697 succinate dehydrogenase flavoprotein subunit from Mycobacterium leprae (584 aa), FASTA scores: opt: 3657, E(): 1.2e-217, (92.55% identity in 590 aa overlap). Also highly similar to others e.g. Q9KZ90|DHSA from Streptomyces coelicolor (584 aa), FASTA scores: opt: 2813, E(): 1.1e-165, (70.5% identity in 586 aa overlap); Q9RVS0|DR0952 from Deinococcus radiodurans (583 aa), FASTA scores: opt: 2203, E(): 4.1e-128, (57.35% identity in 593 aa overlap); P31038|DHSA_RICPR|SDHA|RP128 from Rickettsia prowazekii (596 aa), FASTA scores: opt: 1892, E(): 5.8e-109, (50.0% identity in 588 aa overlap); P10444|DHSA_ECOLI|SDHA|B0723|Z0877|ECS0748 from Escherichia coli strains K12 and O157:H7 (588 aa), FASTA scores: opt: 1844, E(): 5.2e-106, (48.75% identity in 591 aa overlap); etc. Contains PS00504 Fumarate reductase / succinate dehydrogenase FAD-binding site. Cofactor: FAD. Similar to the flavoprotein subunits of other species succinate dehydrogenase and of fumarate reductase. Part of an enzyme complex containing four subunits: a flavoprotein, an iron-sulfur, cytochrome B-556, and an hydrophobic anchor protein. |
| 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). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 and 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza 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). 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). Check for mutants available at TARGET website |
