Gene Rv3509c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Could be involved in valine and isoleucine biosynthesis (at the first step) [catalytic activity: 2-acetolactate + CO(2) = 2 pyruvate]. |
| Product | Probable acetohydroxyacid synthase IlvX (acetolactate synthase) |
| Comments | Rv3509c, (MTV023.16), len: 515 aa. Probable ilvX, acetohydroxyacid synthase, equivalent to Mycobacterium leprae protein described as Acetolactate synthase I, valine sensitive, large subunit Q49865|ILVX|ILVI1|B229_C3_222 (515 aa), FASTA scores: opt: 2762, E(): 8.8e-145, (82.9% identity in 515 aa overlap). Also similar to various enzymes (principally acetohydroxyacid/acetolactate synthases) e.g. Q9AB41|CC0393 thiamine-pyrophosphate-requiring enzyme from Caulobacter crescentus (512 aa), FASTA scores: opt: 1572, E(): 2.8e-79, (50.95% identity in 514 aa overlap); BAB50432|MLL3567 acetolactate synthase I from Rhizobium loti (Mesorhizobium loti) (517 aa), FASTA scores: opt: 1440, E(): 5.2e-72, (47.9% identity in 548 aa overlap); P20906|MDLC_PSEPU benzoylformate decarboxylase from Pseudomonas putida (528 aa), FASTA scores: opt: 356, E(): 2.5e-12, (28.1% identity in 530 aa overlap); Q9L123|SC6D11.33c putative decarboxylase from Streptomyces coelicolor (526 aa), FASTA scores: opt: 325, E(): 1.3e-10, (33.2% identity in 530 aa overlap); Q9RDF9|SCC57A.40c putative acetolactate synthase from Streptomyces coelicolor (564 aa), FASTA scores: opt: 304, E(): 1.9e-09, (28.55% identity in 550 aa overlap); P94783 valine-sensitive acetohydroxy acid synthase from Citrobacter freundii (561 aa), FASTA scores: opt: 278, E(): 5.1e-08, (25.8% identity in 550 aa overlap); Q42767|AHAS acetohydroxyacid synthase from Gossypium hirsutum (Upland cotton) (659 aa), FASTA scores: opt: 278, E(): 5.8e-08, (26.15% identity in 558 aa overlap); etc. Note that other Mycobacterium tuberculosis proteins, e.g. O53250|MTV012.17c|ILVB_MYCTU|Rv3003c|MT3083|MTV012.17c, show better similarity to Acetolactate synthase I. Similar to other enzymes which require TPP. Cofactor: thiamin pyrophosphate (by similarity). |
| Functional category | Intermediary metabolism and respiration |
