亚硫酸氢盐催化胞苷在N4位的转氨作用;已研究了该反应用于将报告基团连接到RNA分子中选定的胞苷残基的适用性。在42 ℃下用乙二胺(pK 1 = 7.6)和亚硫酸氢盐处理3小时后,聚(C)几乎定量转化为聚(N4氨乙基-C)衍生物。该衍生物与N-羟基琥珀酰亚胺酯定量反应;证明了荧光染料nitrohenzofurazan通过该反应与胞苷的连接。为了将亚硫酸氢盐反应引导至大RNA分子内的选定胞苷,RNA与含有缺失的互补DNA杂交。只有单链RNA环中的胞苷(对应于DNA缺失)具有反应性。用这种技术修饰了16 S核糖体RNA的340个碱基的RNA片段中间的两个胞苷。
Bisulfite catalyzes transamination of cytidine at the N4position; the suitability of this reaction for attaching reporter groups to selected cytidine residues in RNA molecules has been investigated. Poly(C) is nearly quantitatively converted to the poly (N4aminoethyl-C) derivative after 3 hrs at 42°C with ethylene diamine (pK1= 7.6) and bisulfite. This derivative reacts quantitatively with N-hydroxysuccinimide esters; the linkage of a fluorescent dye, nitrohenzofurazan, to cytidines by this reaction is demonstrated. To direct the bisulfite reaction to selected cytidines within a large RNA molecule, the RNA is hybridized to complementary DNA containing a deletion. Only the cytidines in the single strand RNA loop (corresponding to the DNA deletion) are reactive. Two cytidines in the middle of a 340 base RNA fragment from 16S rihosomal RNA have been modified by this technique.
