Gene Rv1475c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in tricarboxylic acid cycle [catalytic activity: citrate = cis-aconitate + H2O] |
| Product | Probable iron-regulated aconitate hydratase Acn (citrate hydro-lyase) (aconitase) |
| Comments | Rv1475c, (MTV007.22c), len: 943 aa. Probable acn, iron-regulated aconitate hydratase, similar to many e.g. P70920|ACON_BRAJA aconitate hydratase from Bradyrhizobium japonicum (906 aa), FASTA scores: opt:1912, E(): 0, (54.8% identity in 958 aa overlap); closest to AF0021|AF002133_2 Mycobacterium avium strain GIR10 (961 aa), FASTA scores: opt: 5072, E(): 0, (82.8% identity in 943 aa overlap). Note aconitase has an active (4FE-4S) and an inactive (3FE-4S) forms. The active (4FE-4S) cluster is part of the catalytic site that interconverts citrate, cis-aconitase, and isocitrate. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by proteomics (see citations below). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in culture filtrates of M. tuberculosis H37Rv (See Malen et al., 2007). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (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).
