Efficient inhibition of human AP endonuclease 1 (APE1) via substrate masking by abasic site-binding macrocyclic ligands.
نویسندگان
چکیده
Bis-naphthalene macrocycles, which bind with high affinity and selectivity to abasic sites in DNA, efficiently inhibit their cleavage by APE1 (IC50 = 55-60 nM in the kinetic assay with a model THF substrate). These results demonstrate that substrate masking by non-covalent abasic-site ligands is an efficient strategy for inhibition of APE1.

Distinct roles of Ape1 protein in the repair of DNA damage induced by ionizing radiation or bleomycin.
Ionizing radiation (IR) and bleomycin (BLM) are used to treat various types of cancers. Both agents generate cytotoxic double strand breaks (DSB) and abasic (apurinic/apyrimidinic (AP)) sites in DNA. The human AP endonuclease Ape1 acts on abasic or 3'-blocking DNA lesions such as those generated by IR or BLM. We examined the effect of siRNA-mediated Ape1 suppression on DNA repair and cellular r...

X-ray analysis of enzyme-DNA interactions is very informative in revealing molecular contacts, but provides neither quantitative estimates of the relative importance of these contacts nor information on the relative contributions of specific and nonspecific interactions to the total affinity of enzymes for specific DNA. A stepwise increase in the ligand complexity approach is used to estimate t...
متن کاملAP endonuclease 1 prevents trinucleotide repeat expansion via a novel mechanism during base excision repair
Base excision repair (BER) of an oxidized base within a trinucleotide repeat (TNR) tract can lead to TNR expansions that are associated with over 40 human neurodegenerative diseases. This occurs as a result of DNA secondary structures such as hairpins formed during repair. We have previously shown that BER in a TNR hairpin loop can lead to removal of the hairpin, attenuating or preventing TNR e...
متن کاملA dominant-negative form of the major human abasic endonuclease enhances cellular sensitivity to laboratory and clinical DNA-damaging agents.
Apurinic/apyrimidinic (AP) endonuclease 1 (APE1) is the primary enzyme in mammals for the repair of abasic sites in DNA, as well as a variety of 3' damages that arise upon oxidation or as products of enzymatic processing. If left unrepaired, APE1 substrates can promote mutagenic and cytotoxic outcomes. We describe herein a dominant-negative form of APE1 that lacks detectable nuclease activity a...
متن کاملPre-steady-state kinetic characterization of the AP endonuclease activity of human AP endonuclease 1.
Human AP endonuclease 1 (APE1, REF1) functions within the base excision repair pathway by catalyzing the hydrolysis of the phosphodiester bond 5 ' to a baseless sugar (apurinic or apyrimidinic site). The AP endonuclease activity of this enzyme and two active site mutants were characterized using equilibrium binding and pre-steady-state kinetic techniques. Wild-type APE1 is a remarkably potent e...
