Abstract

The E. coli polynucleotide phosphorylase-catalysed reaction of the deoxynucleoside 5'-diphosphates of 5-methyldeoxycytidine, N4-hydroxydeoxycytidine, deoxyuridine and 5-mercurideoxyuridine with the primers d(pT-T-A-G) and d(pT-T-T-T-T-T) have been studied under conditions where the primer is extended, predominantly, by one or two nucleotide residues. In experiments with 5-mercurideoxyuridine 5'-diphosphate, no 5-mercurideoxy-uridine-containing oligonucleotides were produced. The other three nucleotide analogs were found to be good substrates for E. coli PNPase and the conditions established for synthesis with these analogs will allow the construction of a number of biologically useful types of oligodeoxyribonucleotide.

摘要

在引物主要延伸一两个核苷酸残基的条件下,研究了大肠杆菌多核苷酸磷酸化酶催化的5-甲基脱氧胞苷、N4-羟基脱氧胞苷、脱氧尿苷和5-汞脱氧尿苷的脱氧核苷5'-二磷酸与引物d(pT-T-A-G)和d(pT-T-T-T-T-T)的反应。在用5-汞脱氧尿苷5'-二磷酸进行的实验中,未产生含5-汞脱氧尿苷的寡核苷酸。发现其他三种核苷酸类似物是大肠杆菌PNPase的良好底物,用这些类似物建立的合成条件将允许构建多种具有生物学用途的寡脱氧核糖核苷酸类型。
