  A Noncovalent Approach to Antiparallel β-Sheet Formation

  摘要：

  Four tripeptide chains, when attached to the same end of a hydrogen-bonded duplex (1.2) with the unsymmetrical, complementary sequences of ADAA/DADD, have been brought into proximity, leading to the formation of four hybrid duplexes, 1a.2a, 1a.2b, 1b.2a, and 1b.2b, each of which contains a two-stranded beta-sheet segment. The extended conformations of the peptide chains were confirmed by 1D and 2D NMR. The peptide strands stay registered through hydrogen bonding and the beta-sheets are stabilized by side chain interactions. Two-dimensional NMR data also indicate that the duplex template prevents further aggregation in the peptide segment. When the peptide chains are attached to the two different termini of the duplex template, NMR studies show the presence of a mixture with no clearly defined conformations. In the absence of the duplex template, the tripeptides are found to associate randomly. Finally, isothermal titration calorimetry studies revealed that the hybrid duplex 1a.2a was more stable than either the duplex template or the peptides alone.

  氢键分子双链体的序列特异性。

  摘要：

  基于双链体1.2设计并合成了氢键结合的分子双链体1.3和1.4，它们各自包含一个不匹配的结合位点（1.3中的受体对受体，以及1.4中的供体对受体）。一维和二维NMR研究表明，尽管存在单个错配的结合位点，但双链体1.3和1.4的骨架仍通过形成其余五个H键而保持对准。1.3和1.4的骨架通过在这些位点周围轻微扭曲而调整为存在不匹配的结合位点，从而减轻了两个H键供体（酰胺O）之间或两个受体（酰胺H）之间的正面排斥性相互作用。将1当量的单链2与单链1形成完美匹配的双链体1.2后，添加到1.3或1.4的溶液中，仅添加1.2和单链3或4，被检测到。等温滴定量热法（ITC，在含5％DMSO的氯仿中）表明，双链体1.3和1.4的稳定性比相应的氢键结合的双链体1.2的稳定性差（> 40倍）。这些NMR和ITC结果表明，两条互补单链的配对不受另一条非常相似的单链的影响，后者仅包含一个错误的H键供体或受体，这表

  perfectly hydrogen-bonded duplex 1.2. These NMR and ITC results indicate that the pairing of two complementary single strands is not affected by another very similar single strand that contains only one wrong H-bond donor or acceptor, which demonstrates that the self-assembly of this class of H-bonded duplexes is a highly sequence-specific process. The role of these H-bonded duplexes as predictable and programmable
