General annotation
Gene namemutT3
Rv numberRv0413
FunctionPossibly 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].
ProductPossible mutator protein MutT3 (7,8-dihydro-8-oxoguanine-triphosphatase) (8-oxo-dGTPase) (dGTP pyrophosphohydrolase)
CommentsRv0413, (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.
