Gene Rv2993c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Isomerizes HHDD (2-hydroxy-hept-2,4-diene-1,7-dioate) to OHED (2-oxo-hept-3-ene-1,7-dioate). |
| Product | Possible 2-hydroxyhepta-2,4-diene-1,7-dioate isomerase (HHDD isomerase) |
| Comments | Rv2993c, (MTV012.07c), len: 239 aa. Possible 2-hydroxyhepta-2,4-diene-1,7-dioate isomerase, equivalent to O33119|ML1689|MLCB637.28 possible 2-hydroxyhepta-2,4-diene- 1,7-dioate isomerase from Mycobacterium leprae (242 aa), FASTA scores: opt: 1427, E(): 4.4e-86, (85.9% identity in 241 aa overlap). Also similar to others e.g. Q9LBE3|DR1609 from Deinococcus radiodurans (250 aa), FASTA scores: opt: 723, E(): 5.5e-40, (49.05% identity in 216 aa overlap); O27551|MTH1507 from Methanothermobacter thermautotrophicus (260 aa), FASTA scores: opt: 708, E(): 5.4e-39, (52.1% identity in 213 aa overlap); Q9HQR6|VNG1037G|HPCE from Halobacterium sp. (strain NRC-1) (244 aa), FASTA scores: opt: 590, E(): 2.7e-31, (43.65% identity in 220 aa overlap); etc. Start chosen by homology, but ORF could continue upstream. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). 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 identified by microarray analysis and down-regulated after 24h and 96h 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). Check for mutants available at TARGET website |
