Gene Rv2540c (aroC)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved at the seventh step in the biosynthesis of chorismate within the biosynthesis of aromatic amino acids (the shikimate pathway) [catalytic activity: 5-O-(1-carboxyvinyl)-3-phosphoshikimate = chorismate + orthophosphate]. |
| Product | Probable chorismate synthase AroF (5-enolpyruvylshikimate-3-phosphate phospholyase) |
| Comments | Rv2540c, (MTCY159.16), len: 401 aa. Probable aroF (alternate gene name: aroC), chorismate synthase, equivalent to Q9CCS6|AROF|ML0516 putative chorismate synthase from Mycobacterium leprae (407 aa), FASTA scores: opt: 2278, E(): 6.2e-123, (88.05% identity in 401 aa overlap). Also highly similar to many e.g. Q9X5D0|AROC_CORGL from Corynebacterium glutamicum (Brevibacterium flavum) (410 aa), FASTA scores: opt: 1811, E(): 3e-96, (70.3% identity in 397 aa overlap); Q9KXQ4|AROC_STRCO|AROF|SC9C5.20c from Streptomyces coelicolor (394 aa), FASTA scores: opt: 1710, E(): 1.7e-90, (67.0% identity in 385 aa overlap); Q9KCB7|AROC_BACHD|AROF|BH1656 from Bacillus halodurans (390 aa), FASTA scores: opt: 1196, E(): 3.9e-61, (48.7% identity in 386 aa overlap); etc. Contains PS00788 Chorismate synthase signature 2. Belongs to the chorismate synthase family. Cofactor: reduced flavin, NADH |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by proteomics at the Statens Serum Institute (Denmark) (See Rosenkrands et al., 2000). Identified in the culture supernatant of M. tuberculosis H37Rv using mass spectrometry (See Mattow et al., 2003). Identified by mass spectrometry in the culture filtrate and whole cell lysates of M. tuberculosis H37Rv but not the 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). 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).
