Gene Rv1160
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | 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. MUTT2 specifically degrades 8-oxo-dGTP to the monophosphate. |
| Product | Probable mutator protein MutT2 (7,8-dihydro-8-oxoguanine-triphosphatase) (8-oxo-dGTPase) |
| Comments | Rv1160, (MTCI65.27), len: 141 aa. Probable mutT2, mutator protein or homolog (see citation below). More similar to D908197|g1742860 MutT homolog from Escherichia coli (135 aa), FASTA scores: opt: 226, E():1.1e-08, (39.7% identity in 116 aa overlap); than to MUTT_ECOLI|P08337 mutator mutt protein from Escherichia coli (129 aa), FASTA scores: opt: 180, E(): 1.2e-05, (27.1% identity in 129 aa overlap). Contains PS00893 mutT domain signature. |
