Unit Definition

One unit will cleave 50% of 0.5 pmol of double-stranded DNA oligomer substrate (8-oxoguanine−mutated) in 10 min at 25 °C.

Physical form

Solution in 50% glycerol containing 50 mM potassium HEPES, pH 7.5, 1 mM DTT, 1 mM EDTA, and 200 mM NaCl.


Fpg Protein from Escherichia coli has been used for the assessment of DNA oxidative damage using comet assay.

Biochem/physiol Actions

Formamidopyrimidine-DNA glycosylase (Fpg) cleaves double-stranded DNA containing the damaged base 8-oxo-7,8-dihydroguanine. It functions as an N-glycosylase and apurinic/apyrimidinic lyase.

General description

Formamidopyrimidine-DNA glycosylase (Fpg) is a DNA repair enzyme found in Escherichia coli, which contains one zinc atom. Proximal to its C-terminal, it contains a zinc-finger motif of CC/CC type.
