重组蛋白设计允许具有不同功能和响应行为的模块化蛋白结构域容易地组合。包含这些蛋白质结构域可以使重组蛋白对其环境具有复杂的响应(例如,温度触发的聚集,随后酶介导的切割用于药物递送或pH触发的构象变化和自组装,导致通过相邻互补残基的结构稳定化)。这些“聪明”的行为可以通过氨基酸的身份和序列,化学修饰和添加其他成分来调节。各种各样的结构域和肽具有智能行为。在这篇综述中,我们将专注于蛋白质的自组装或构象变化的设计,由于刺激,如温度或pH值的变化。在天然和重组蛋白质的环境响应行为可以追溯到特定的氨基酸序列,可用于模块化蛋白质的设计。这些序列可以单独使用或结合使用,以产生对多种刺激的复杂反应,包括温度,pH值和盐,并引起结构变化和自组装。
Recombinant protein design allows modular protein domains with different functionalities and responsive behaviors to be easily combined. Inclusion of these protein domains can enable recombinant proteins to have complex responses to their environment (e.g., temperature-triggered aggregation followed by enzyme-mediated cleavage for drug delivery or pH-triggered conformational change and self-assembly leading to structural stabilization by adjacent complementary residues). These “smart” behaviors can be tuned by amino acid identity and sequence, chemical modifications, and addition of other components. A wide variety of domains and peptides have smart behavior. In this review, we will focus on protein designs for self-assembly or conformational changes due to stimuli such as shifts in temperature or pH. Environmentally-responsive behavior in natural and recombinant proteins can be traced to specific amino acid sequences that can be used in modular protein design. These sequences can be used alone or in conjunction to create complex responses to multiple stimuli, including temperature, pH, and salt, and to cause structural changes and self-assembly.
