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

This reaction takes place in the 'nucleus' and is mediated by the 'DNA N-glycosylase activity' of 'G/T mismatch-specific thymine DNA glycosylase (EC 3.2.2.-)'.
