Gene Rv0409
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved at the first step (of two) in the conversion of acetate to acetyl-CoA [catalytic activity: ATP + acetate = ADP + acetyl phosphate]. |
| Product | Probable acetate kinase AckA (acetokinase) |
| Comments | Rv0409, (MTCY22G10.05), len: 385 aa. Probable ackA, acetate kinase, highly similar to others e.g. ACKA_BACSU|P37877 acetate kinase from Bacillus subtilis (395 aa), FASTA scores: opt: 974, E(): 0, (43.5% identity in 393 aa overlap); etc. Contains PS01075 Acetate and butyrate kinases family signature 1, PS00758 ArgE / dapE / ACY1/ CPG2 / yscS family signature 1. Belongs to the acetokinase family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | 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). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
