in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in valine and isoleucine biosynthesis (at the first step) [catalytic activity: 2-acetolactate + CO(2) = 2 pyruvate]. |
| Product | Acetolactate synthase (large subunit) IlvB1 (acetohydroxy-acid synthase) |
| Comments | Rv3003c, (MT3083, MTV012.17c), len: 618 aa. ilvB1, acetolactate synthase, large subunit, equivalent or highly similar to others e.g. O33112|ILVB_MYCLE|MLCB637.20|ML1696 from Mycobacterium leprae (625 aa), FASTA scores: opt: 3653, E(): 5.4e-208, (87.1% identity in 627 aa overlap); Q59498|ILVB_MYCAV from Mycobacterium avium (621 aa), FASTA scores: opt: 3473, E(): 2.3e-197, (84.7% identity in 614 aa overlap); P42463|ILVB_CORGL from Corynebacterium glutamicum (Brevibacterium flavum) (626 aa), FASTA scores: opt: 2754, E(): 5.9e-155, (65.8% identity in 589 aa overlap); etc. Contains PS00187 Thiamine pyrophosphate enzymes signature. Cofactor: thiamine pyrophosphate, and magnesium (by similarity). Note that previously known as ilvB. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by proteomics at the Statens Serum Institute (Denmark) (See Rosenkrands et al., 2000). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). Translational start site supported by proteomics data (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). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
