  • 功能：
    Specifically hydrolyzes both 8-oxo-deoxyguanosine triphosphate (8-oxo-dGTP) and 8-oxo-guanosine triphosphate (8-oxo-GTP) to the related monophosphates, thereby cleaning up the nucleotide pools and preventing misincorporation of 8-oxoGua into DNA and RNA. It prevents replicational errors by removing an oxidatively damaged form of guanine (8-oxo-dGTP) from DNA and the nucleotide pool. 8-oxo-dGTP can be inserted opposite dA and dC residues of template DNA with almost equal efficiency thus leading to A.T to G.C transversions. MutT may also ensure transcriptional fidelity, removing 8-oxo-GTP from the ribonucleotide triphosphate pool. However, due to the lower efficiency of RNA polymerase 8-oxo-GTP incorporation, MutT is probably not a major contributor to transcriptional fidelity. It also hydrolyzes 8-oxo-dGDP and 8-oxo-GDP to their monophosphate form. In vitro, can also use dGTP, dGDP and other various nucleoside di- and triphosphates, with much lower efficiency. Works cooperatively with MutM and MutY to prevent accumulation in the DNA of oxidized guanine residues.

    3. The MutT functions are not needed under anaerobic condition, yet the level of the MutT protein in cell is kept constant, probably for preparing for sudden changes of oxygen pressure. PMID: 21147134
    4. MutT hydrolyzes four types of 8-oxoGua (8-oxo-7,8-dihydroguanine)-containing nucleoside diphosphates and triphosphates to the related monophosphates, thereby preventing misincorporation of 8-oxoGua into DNA and RNA. PMID: 15850400
    5. transient state kinetic analysis of the reaction pathway of mutT; findings confirm an iso kinetic mechanism and explain the preferred hydrolysis of 8-oxo-dGTP PMID: 16285737
    6. These results indicate that mutT plays important roles in mutagenesis induced by 2-OH-dATP and 8-OH-dGTP in vivo. PMID: 17150583
    7. The mutT defect does not elevate chromosomal fragmentation in Escherichia coli because of the surprisingly low levels of MutM/MutY-recognized DNA modifications. PMID: 17616589
