Gene Rv2988c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in leucine biosynthesis (at the second step) [catalytic activity: 3-isopropylmalate = 2-isopropylmaleate + H(2)O (also catalyses 2-isopropylmaleate + H(2)O = 3-hydroxy-4-methyl-3-carboxypentanone)]. |
| Product | Probable 3-isopropylmalate dehydratase (large subunit) LeuC (isopropylmalate isomerase) (alpha-IPM isomerase) (IPMI) |
| Comments | Rv2988c, (MTV012.02c), len: 473 aa. Probable leuC, 3-isopropylmalate dehydratase, large subunit, equivalent to O33123|LEU2_MYCLE 3-isopropylmalate dehydratase small subunit from Mycobacterium leprae (476 aa), FASTA scores: opt: 2818, E(): 1.3e-171, (88.75% identity in 471 aa overlap). Also highly similar to many e.g. Q44427|LEU2_ACTTI from Actinoplanes teichomyceticus (485 aa), FASTA scores: opt: 1958, E(): 6.5e-117, (71.0% identity in 479 aa overlap); P55251|LEU2_RHIPU from Rhizomucor pusillus (755 aa), FASTA scores: opt: 1937, E(): 1.9e-115, (61.25% identity in 467 aa overlap) (C-terminus longer); P30127|LEU2_ECOLI|LEUC|B0072 from Escherichia coli strain K12 (465 aa), FASTA scores: opt: 1896, E(): 5.5e-113, (61.6% identity in 456 aa overlap); etc. Contains PS00450 Aconitase family signature. Belongs to the aconitase/IPM isomerase family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cell wall fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Transcriptomics | mRNA identified by DNA microarray analysis: up-regulated at high temperatures, and down-regulated after 4h, 24h and 96h of starvation (see citations 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). Disruption of this gene results in growth defect of H37Rv in vitro, 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 |
