Gene Rv3140
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Function unknown, but involved in lipid degradation. |
| Product | Probable acyl-CoA dehydrogenase FadE23 |
| Comments | Rv3140, (MTCY03A2.18c), len: 401 aa. Probable fadE23, acyl-CoA dehydrogenase (1.3.99.-) (see citation below), equivalent to O32891|MLCB1779.31|FADE23|ML0660 putative acyl-CoA dehydrogenase from Mycobacterium leprae (400 aa), FASTA scores: opt: 2307, E(): 3e-136, (89.5% identity in 401 aa overlap). Also similar to others e.g. Q9HUH1|PA4994 from Pseudomonas aeruginosa (402 aa), FASTA scores: opt: 1558, E(): 1.2e-89, (61.0% identity in 400 aa overlap); O31251 from Acinetobacter sp. ADP1 (401 aa), FASTA scores: opt: 1509, E(): 1.3e-86, (58.2% identity in 402 aa overlap); Q9K6D1|ACDA or BH3798 from Bacillus halodurans (380 aa), FASTA scores: opt: 612, E(): 8.4e-31, (38.2% identity in 293 aa overlap); Q9AHX9|FADFX from Pseudomonas putida (375 aa), FASTA scores: opt: 584, E(): 4.6e-29, (32.7% identity in 379 aa overlap); etc. Could belong to the acyl-CoA dehydrogenases family. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011). |
| Transcriptomics | mRNA identified by DNA microarray analysis: gene induced by isoniazid (INH) or ethionamide treatment, and down-regulated after 4h, 24h and 96h of starvation (see citations below). |
| 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). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Check for mutants available at TARGET website |
