Gene Rv3516
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Could possibly oxidize fatty acids using specific components [catalytic activity: (3S)-3-hydroxyacyl-CoA = trans-2(or 3)-enoyl-CoA + H(2)O]. |
| Product | Possible enoyl-CoA hydratase EchA19 (enoyl hydrase) (unsaturated acyl-CoA hydratase) (crotonase) |
| Comments | Rv3516, (MTV023.23), len: 263 aa. Possible echA19, enoyl-CoA hydratase, similar to other e.g. Q9ZHG2|ECHA1 from Rhodococcus fascians (275 aa) FASTA scores: opt: 613, E(): 6.4e-32, (45.15% identity in 259 aa overlap); P76082|PAAF_ECOLI|B1393 from Escherichia coli strain K12 (255 aa), FASTA scores: opt: 523, E(): 3.3e-26, (33.6% identity in 256 aa overlap); Q9I393|PA1629 from Pseudomonas aeruginosa (261 aa), FASTA scores: opt: 475, E(): 3.8e-23, (36.85% identity in 247 aa overlap); etc. Also similar to many carnitine racemases eg BAB52369|MLL6015 from Rhizobium loti (Mesorhizobium loti) (257 aa), FASTA scores: opt: 546, E(): 1.1e-27, (36.65% identity in 251 aa overlap). Similar to several putative enoyl-CoA hydratases from Mycobacterium tuberculosis, e.g. P96404|ECHA1|Rv0222|MTCY08D5.17 (262 aa), FASTA scores: opt: 630, E(): 5.1e-33, (44.5% identity in 254 aa overlap); and O53783|ECHA5|Rv0675|MTV040.03 (263 aa) FASTA scores: opt: 499, E(): 1.1e-24, (40.5% identity in 252 aa overlap). Could belong to the enoyl-CoA hydratase/isomerase family. |
| Functional category | Lipid metabolism |
| Proteomics | 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). |
| Transcriptomics | mRNA level (identified by real-time quantitative RT-PCR) increased 24 and 72h after cultured macrophages infection (see citation below). |
| Operon | Rv3516 and Rv3517 are co-transcribed, by RT-PCR (see Roback et al., 2007). |
| 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 strain (see Sassetti 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 |
