  γ-AApeptides bind to RNA by mimicking RNA-binding proteins

  摘要：

  蛋白质与RNA之间的相互作用对许多细胞过程至关重要，包括RNA的转录和加工、翻译以及病毒感染。我们在这里报道一种γ-AA肽，它能够模拟HIV-1 Tat蛋白，并以纳摩尔亲和力结合HIV和BIV的TAR RNA，这一亲和力与Tat的RNA结合片段（氨基酸49-58）相当。该相互作用能抵抗大量tRNA的存在。由于对蛋白水解的抵抗以及无限的多样化潜力，γ-AA肽可能会成为调节RNA-蛋白相互作用的新型肽模仿物。

  The DNA-templated polymerization of synthetic building blocks provides a potential route to the laboratory evolution of sequence-defined polymers with structures and properties not necessarily limited to those of natural biopolymers. We previously reported the efficient and sequence-specific DNA-templated polymerization of peptide nucleic acid (PNA) aldehydes. Here, we report the enzyme-free, DNA-templated polymerization of side-chain-functionalized PNA tetramer and pentamer aldehydes. We observed that polymerization of tetramer and pentamer PNA building blocks with a single lysine-based side chain at various positions in the building block could proceed efficiently and sequence specifically. In addition, DNA-templated polymerization also proceeded efficiently and in a sequence-specific manner with pentamer PNA aldehydes containing two or three lysine side chains in a single building block to generate more densely functionalized polymers. To further our understanding of side-chain compatibility and expand the capabilities of this system, we also examined the polymerization efficiencies of 20 pentamer building blocks each containing one of five different side-chain groups and four different side-chain regio- and stereochemistries. Polymerization reactions were efficient for all five different side-chain groups and for three of the four combinations of side-chain regio- and stereochemistries. Differences in the efficiency and initial rate of polymerization correlate with the apparent melting temperature of each building block, which is dependent on side-chain regio- and stereochemistry but relatively insensitive to side-chain structure among the substrates tested. Our findings represent a significant step toward the evolution of sequence-defined synthetic polymers and also demonstrate that enzyme-free nucleic acid-templated polymerization can occur efficiently using substrates with a wide range of side-chain structures, functionalization positions within each building block, and functionalization densities.
