Gene Rv1143
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Required for bile acid synthesis and for catabolism of branched-chain fatty acids |
| Product | Probable alpha-methylacyl-CoA racemase Mcr (2-methylacyl-CoA racemase) (2-arylpropionyl-CoA epimerase ) |
| Comments | Rv1143, (MTCI65.10), len: 360 aa. Probable mcr, alpha-methylacyl-CoA racemase. Strong similarity to other alpha-methylacyl-CoA racemases and also some similarity to L-carnitine dehydratase e.g. U89905|g1552373 methylacyl-CoA racemase alpha from Norway rat (361 aa), FASTA scores: opt: 1035, E():0, (47.2% identity in 339 aa overlap). Equivalent to (but longer than) Z94723|MLCB33_13 Mycobacterium leprae (253 aa) (85.3% identity in 245 aa overlap). Also similar to Mycobacterium tuberculosis putative racemases Rv0855, Rv1866, Rv3272. |
| 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 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). Disruption of this gene provides a growth advantage 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 |
