This article presents new data on nucleotide incision repair (NIR) activity of apurinic/apyrimidinic endonuclease Apn1 of , which is known as a key player of the base excision DNA repair (BER) pathway, see "Yeast structural gene (APN1) for the major apurinic endonuclease: homology to Escherichia coli endonuclease IV" [1], "Abasic sites in DNA: repair and biological consequences in Saccharomyces cerevisiae" [2] and "Characterisation of new substrate specificities of Escherichia coli and Saccharomyces cerevisiae AP endonucleases" [3]. The characterization of NIR activity of wild type Apn1 and mutant form Ape1 H83A were made by denaturing PAGE analysis, and MD simulations of Apn1 complexed with DNA containing 5,6-dihydro-2'-deoxyuridine (DHU) and 2-aminopurine (2-aPu) residues. This data article is associated to the manuscript titled "Apurinic/apyrimidinic endonuclease Apn1 from is recruited to the nucleotide incision repair pathway: kinetic and structural features" [4]. http://creativecommons.org/licenses/by/4.0/
本文展示了关于嗜热栖热放线菌脱嘌呤/脱嘧啶内切核酸酶Apn1的核苷酸切口修复（NIR）活性的新数据，Apn1是碱基切除DNA修复（BER）途径的关键参与者，见“酵母主要脱嘌呤内切核酸酶的结构基因（APN1）：与大肠杆菌内切核酸酶IV的同源性”[1]、“DNA中的无碱基位点：酿酒酵母中的修复及生物学后果”[2]以及“大肠杆菌和酿酒酵母AP内切核酸酶新底物特异性的表征”[3]。通过变性聚丙烯酰胺凝胶电泳分析以及对与含有5,6 - 二氢 - 2'-脱氧尿苷（DHU）和2 - 氨基嘌呤（2 - aPu）残基的DNA复合的Apn1进行分子动力学模拟，对野生型Apn1和突变形式Ape1 H83A的NIR活性进行了表征。本数据文章与题为“嗜热栖热放线菌的脱嘌呤/脱嘧啶内切核酸酶Apn1被招募到核苷酸切口修复途径：动力学和结构特征”[4]的手稿相关。http://creativecommons.org/licenses/by/4.0/
