. "At the beginning of this reaction, 1 molecule of 'hNTH1 glycosylase: foramidopyrimidine complex' is present. At the end of this reaction, 1 molecule of 'formamidopyrimidine', and 1 molecule of 'DNA containing a hNTH1-bound apurinic/apyrimidinic site' are present.

This reaction takes place in the 'nucleus' and is mediated by the 'pyrimidine-specific oxidized base lesion DNA N-glycosylase activity' of 'hNTH1'.
