Gene Rv1492
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in propionic acid fermentation. Catalyzes the isomerization of succinyl-CoA to methylmalonyl-CoA during synthesis of propionate from tricarboxylic acid-cycle intermediates [catalytic activity: (R)-2-methyl-3-oxopropanoyl-CoA = succinyl- CoA] |
| Product | Probable methylmalonyl-CoA mutase small subunit MutA (MCM) |
| Comments | Rv1492, (MTCY277.14), len: 615 aa. Probable mutA, Methylmalonyl-CoA mutase small-subunit, strong similarity to e.g. MUTA_STRCM|Q05064 methylmalonyl-CoA mutase beta-subunit from Streptomyces cinnamonensis (616 aa), FASTA scores: opt: 1512, E(): 0, (45.9% identity in 628 aa overlap). Contains PS00213 Lipocalin signature, PS00544 Methylmalonyl-CoA mutase signature. Belongs to the methylmalonyl-CoA mutase family. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the cytosol, cell wall, and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). 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 | 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 strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Growth of M. tuberculosis H37Rv mutAB mutant on propionate is comparable to H37Rv, with and without vitamin B12 supplement; mutant is unable to grow on B12-supplemented propionate with 3-nitropropionate; prpDC-mutAB mutant is unable to grow on B12-supplemented propionate (See Savvi et al., 2008).
