Gene Rv0751c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Catalyzes the NAD-dependent, reversible oxidation of 3-hydroxbutyrate to methylmalonate [catalytic activity: 3-hydroxy-2-methylpropanoate + NAD+ = 2-methyl-3-oxopropanoate + NADH]. |
| Product | Probable 3-hydroxyisobutyrate dehydrogenase MmsB (hibadh) |
| Comments | Rv0751c, (MTV041.25c), len: 294 aa. Probable mmsB, 3-hydroxyisobutyrate dehydrogenase, highly similar to others e.g. NP_102847.1|NC_002678 3-hydroxyisobutyrate dehydrogenase from Mesorhizobium loti (294 aa); NP_420167.1|NC_002696 3-hydroxyisobutyrate dehydrogenase from Caulobacter crescentus (298 aa); A32867 3-hydroxyisobutyrate dehydrogenase from Rattus norvegicus (346 aa); etc. Also similar to methylmalonate semialdehyde dehydrogenases e.g. M84911|PSE MMSRAB_3 methylmalonate semialdehyde dehydrogenase from Pseudomonas aeruginosa (298 aa), FASTA scores: opt: 786, E(): 0, (45.8% identity in 297 aa overlap). Also similar to 6-phosphogluconate dehydrogenases from Mycobacterium tuberculosis e.g. Rv1122 and Rv1844c. Contains PS00895 3-hydroxyisobutyrate dehydrogenase signature. Belongs to the 3-hydroxyisobutyrate dehydrogenase 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 de Souza et al., 2011) (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 strain (see Sassetti 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 |
