In this work, we demonstrated that (i) salts of RNA/DNA segments were capable of catalyzing Knoevenagel condensation at physiological pH 7.0 with efficiency comparable to one of the best enzymes, porcine pancreatic lipase (PPL); and (ii) a broad scope of substrates could be successfully used in this reaction. Velocity of catalysis was positively correlated with the content of GC nucleosides in DNA/RNA;
在这项工作中,我们证明(i)RNA / DNA片段的盐能够在生理pH 7.0下催化Knoevenagel缩合,其效率可与最佳酶之一-猪胰
脂肪酶(PPL)相媲美;(ii)可以在该反应中成功使用广泛范围的底物。催化速度与DNA / RNA中GC核苷的含量呈正相关。而DNA片段中的3D组织在很大程度上促进了催化转化次数的增加。对反应机理的深入了解(基于动力学的定量分析)阐明了底物结合机理中DNA,RNA和PPL之间的一般相似性。
