. "At the beginning of this reaction, 1 molecule of 'UNG2 glycosylase:uracil complex' is present. At the end of this reaction, 1 molecule of 'DNA containing UNG2-bound apurinic/apyrimidinic site', and 1 molecule of 'Uracil' are present.

This reaction takes place in the 'nucleus' and is mediated by the 'uracil DNA N-glycosylase activity' of 'UNG2'.
