Gene Rv3670
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Thought to be involved in detoxification reactions following oxidative damage to lipids. Biotransformation enzyme that catalyzes the hydrolysis of epoxides: aromatic hydrocarbons catabolism [catalytic activity: an epoxide + H(2)O = a glycol]. |
| Product | Possible epoxide hydrolase EphE (epoxide hydratase) (arene-oxide hydratase) |
| Comments | Rv3670, (MTV025.018), len: 327 aa. Possible ephE, epoxide hydrolase (see citation below), equivalent to Q9CB96|ML2297 putative hydrolase from Mycobacterium leprae (324 aa), FASTA scores: opt: 1799, E(): 7.2e-105, (80.55% identity in 324 aa overlap). Also similar to many hydrolases (epoxide hydrolases) and hypothetical proteins e.g. Q9X931|SCH5.29 putative hydrolase from Streptomyces coelicolor (324 aa), FASTA scores: opt: 687, E(): 1.4e-35, (40.65% identity in 327 aa overlap); Q9RRE3|DR2549 epoxide hydrolase-related protein from Deinococcus radiodurans (278 aa), FASTA scores: opt: 321, E(): 8.2e-13, (32.15% identity in 311 aa overlap); Q9K3Q1|2SCG4.13 putative hydrolase from Streptomyces coelicolor (292 aa), FASTA scores: opt: 295, E(): 3.5e-11, (30.18% identity in 275 aa overlap); Q9S7P1 epoxide hydrolase from Oryza sativa (Rice) (322 aa), FASTA scores: opt: 289, E(): 9.1e-11, (28.7% identity in 338 aa overlap); O23227|C7A10.830|AT4G36530 epoxide hydrolase from Arabidopsis thaliana (Mouse-ear cress) (378 aa) FASTA scores: opt: 287, E(): 1.4e-10, (26.1% identity in 272 aa overlap); Q21147|K02F3.6 epoxide hydrolase from Caenorhabditis elegans (386 aa), FASTA scores: opt: 283, E(): 2.5e-10, (33.35% identity in 156 aa overlap); etc. Also similar to P95276|EPHB|Rv1938|MTCY09F9.26c from Mycobacterium tuberculosis (356 aa), FASTA scores: opt: 296, E(): 3.6e-11, (29.7% identity in 340 aa overlap). Contains PS00213 Lipocalin signature. Similar to alpha/beta hydrolase fold. |
| Functional category | Virulence, detoxification, adaptation |
| Proteomics | 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 of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Mutant | 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 for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
