A deoxyribonucleic acid (DNA) duplex with a chain length of 46 which contain binding sites for catabolite gene activator protein and ribonucleic acid (RNA) polymerase was synthesized by the solid-phase phosphotriester method, involving condensation of tetramer or pentamer blocks. Eleven oligonucleotide blocks were used to elongate each chain, beginning from polystyrene-linked N-protected 3'-succinyldeoxynucleoside. The estimated overall yields of upper and lower chains were 18% and 17%, respectively. The products were purified by reversed phase chromatography and characterized by sequence analysis using the Maxam-Gilbert method.
一种链长为46的脱氧核糖核酸(DNA)双链被合成,具有用于代谢基因激活蛋白和 RNA 聚合酶的结合位点,采用固相磷三酯法合成,涉及四聚体或五聚体片段的缩合。使用了十一种寡核苷酸片段来延长每条链,从聚苯乙烯连接的 N 保护的 3'-琥珀酰脱氧核苷开始。上链和下链的总体产率分别为18%和17%。产品通过反相色谱纯化,并通过 Maxam-Gilbert 方法进行序列分析以进行表征。
