Gene Rv2740
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Biotransformation enzyme that catalyzes the hydrolysis of epoxides (alkene oxides, oxiranes) and arene oxides to less reactive and more water soluble dihydrodiols by the trans addition of water. Involved in detoxification reactions following oxidative damage to lipids [catalytic activity: an epoxide + H(2)O = a glycol]. |
| Product | Epoxide hydrolase |
| Comments | Rv2740, (MTV002.05), len: 149 aa. EphG, Epoxide hydrolase, proven biochemically (see Unge et al. 2005), similar to limonene-1,2-epoxide hydrolase capable of hydrolyzing long or bulky lipophilic epoxides. Equivalent, but shorter 17 aa, to Q9CCC2|ML0984 (alias Q49850 but longer) hypothetical protein from Mycobacterium leprae (164 aa), FASTA scores: opt: 481, E(): 9.7e-26, (52.0% identity in 150 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). |

| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the 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 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). |
| 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). 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 |
