合成生物学是一门新兴的技术学科,旨在设计和构建新型生物系统,以满足紧迫的社会需求。然而,工程生物学仍然需要大量的试验和错误,因为我们缺乏有效的方法将基本“部分”连接到按预测运行的高阶网络中。制定提高设计性能和复杂性的策略需要考虑两个总体视角:“自下而上”和“自上而下”的考虑因素。使用这个框架,我们描述了一个概念模型,用于开发新型生物系统,该系统以可预测的方式发挥作用并与现有生物成分相互作用。我们在三个主题领域讨论这个模型:生化转化、细胞设备和治疗,以及扩展生命化学的方法。在第一台合成生物学设备建成十年后,超越现有事物并关注可能存在的事物的动力正在开创一个设计生物学的时代。
Synthetic biology is a nascent technical discipline that seeks to enable the design and construction of novel biological systems to meet pressing societal needs. However, engineering biology still requires much trial and error because we lack effective approaches for connecting basic “parts” into higher-order networks that behave as predicted. Developing strategies for improving the performance and sophistication of our designs is informed by two overarching perspectives: “bottom-up” and “top-down” considerations. Using this framework, we describe a conceptual model for developing novel biological systems that function and interact with existing biological components in a predictable fashion. We discuss this model in the context of three topical areas: biochemical transformations, cellular devices and therapeutics, and approaches that expand the chemistry of life. Ten years after the construction of synthetic biology's first devices, the drive to look beyond what does exist to what can exist is ushering in an era of biology by design.
