Gene Rv1142c
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 | Probable enoyl-CoA hydratase EchA10 (enoyl hydrase) (unsaturated acyl-CoA hydratase) (crotonase) |
| Comments | Rv1142c, (MTCI65.09c), len: 268 aa. Probable echA10, enoyl-CoA hydratase, similar to others e.g. CAA66096.1|X97452 enoyl-CoA isomerase from Escherichia coli (262 aa), FASTA scores: opt: 525, E(): 1.3e-26, (35.1% identity in 251 aa overlap); NP_420658.1|NC_002696 enoyl-CoA hydratase/isomerase family protein from Caulobacter crescentus (267 aa); NP_438092.1|NC_003078 putative enoyl-CoA hydratase protein from Sinorhizobium meliloti (263 aa); etc. Also similarity with naphthoate synthases. Also highly similar to upstream ORF Rv1141c|MTCI65.08c|echA11 probable enoyl-CoA hydratase from Mycobacterium tuberculosis (268 aa), FASTA score: opt: 1225, E(): 0, (72.3% identity in 267 aa overlap). |
| Functional category | Lipid metabolism |
| 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 whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 24h of starvation (see citation 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). 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 |
