3.6.1.55 | 8-oxo-dGTP + H2O | Escherichia coli | 8-oxoguanine (8-oxo-7,8-dihydroguanine) is produced in nucleic acids as well as in nucleotide pools of cells, by reactive oxygen species normally formed during cellular metabolic processes. MutT protein of Escherichia coli specifically degrades 8-oxoGua-containing deoxyribo- and ribonucleoside triphosphates to corresponding nucleoside monophosphates, thereby preventing misincorporation of 8-oxoguanine into DNA and RNA, which would cause mutation and phenotypic suppression, respectively | 8-oxo-dGMP + diphosphate | - |
