ID 3.5.4.32 DE 8-oxoguanine deaminase. CA 8-oxoguanine + H(+) + H2O = NH4(+) + urate. CC -!- 8-oxoguanine is formed via the oxidation of guanine within DNA by CC reactive oxygen species. CC -!- If uncorrected, this modification leads to the incorporation of CC 8-oxoG:A mismatches and eventually to G:C to T:A transversions. DR Q9I6Z0, OXODE_PSEAE; //
