Accepted name: |
8-oxoguanine deaminase |
Reaction: |
8-oxoguanine + H2O = urate + NH3 |
Glossary: |
8-oxoguanine = 2-amino-7,9-dihydro-1H-purine-6,8-dione |
Other name(s): |
8-OGD |
Systematic name: |
8-oxoguanine aminohydrolase |
Comments: |
Zn2+ is bound in the active site. 8-Oxoguanine is formed via the oxidation of guanine within DNA by reactive oxygen species. If uncorrected, this modification leads to the incorporation of 8-oxoG:A mismatches and eventually to G:C to T:A transversions.
