Gene Rv0413
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Possibly involved in the go system responsible for removing an oxidatively damaged form of guanine (7,8-dihydro-8-oxoguanine) from DNA and the nucleotide pool. 8-oxo-dGTP is inserted opposite DA and DC residues of template DNA with almost equal efficiency thus leading to A.T to G.C transversions. MutT specifically degrades 8-oxo-dGTP to the monophosphate [catalytic activity: 8-oxo-dGTP + H2O = 8-oxo-dGMP + pyrophosphate]. |
| Product | Possible mutator protein MutT3 (7,8-dihydro-8-oxoguanine-triphosphatase) (8-oxo-dGTPase) (dGTP pyrophosphohydrolase) |
| Comments | Rv0413, (MTCY22G10.10), len: 217 aa. Possible mutT3, mutator protein (see citation below), showing some similarity with e.g. MUTT_PROVU|P32090 mutator mutt protein from Proteus vulgaris (112 aa), FASTA scores: opt: 151, E(): 0.0008, (40.7% identity in 59 aa overlap). Seems to belong to the NUDIX hydrolase family. |
| Functional category | Information pathways |
| Proteomics | Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). |
| 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 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 |
