Apurinic/apyrimidinic endonuclease 1/redox factor-1 (APE1/Ref-1) is a multifunctional protein that plays a central role in the cellular response to DNA damage and redox regulation against oxidative stress. APE1/Ref-1 functions in...
Three kinds of apurinic/apyrimidinic (AP) DNA endonuclease, APcI, APcII, APcIII, were purified from rat liver chromatin through 1M KCl extraction, DEAE-trisacryl ion exchange chromatography. Sephadex G-150 gel filtration and AP...
An experiment was designed to investigate the reaction mechanism of AP (apurinic or apyrimidinic) DNA endonucleases (APcI, APcII, APcIII) purified from rat liver chromatin. Sulfhydryl compounds (2-mercaptoethanol, dithiothreitol) brought about...
Apurinic/apyrimidinic endonuclease 1 (APE1) is a multifunctional enzyme involved in the base excision repair (BER) pathway, which repairs oxidative base damage caused by endogenous and exogenous agents. APE1 acts as...
PURPOSE: 7-Bromomethylbenz[alpha]anthracene is a known mutagen and carcinogen. The mutagenic potency of its two major DNA adducts, i.e., N2-(benz[alpha]anthracen-7-ylmethyl)-2'-deoxyguanosine (b[alpha]a2G) and N6-(benz[alpha]anthracen-7-ylmethyl)-2'-deoxyadenosine (b[alpha]a6A), as well as the simpler benzylated analogs,...
