分子进化,简单分子的自组织向复杂的功能系统,提供了一个新的策略,仿生建筑学和理解生命的复杂过程的观点。然而,制造包括不同类型的单元的系统仍然存在许多挑战,这些单元彼此相互作用以执行期望的功能。挑战来自于缺乏与给定环境相协调的稳定性、动态属性和功能。提出了一种由简单肽和卟啉组成的共组装纤维体系。这种材料被认为是分子的益生元组装体,其可以在“益生元汤”中的可见光的帮助下相当稳定和灵活地自功能化;酸性(pH 2),热(70摄氏度)和含矿物质(Na+,Ti4+,Pt 2+等)的水。具有自矿化反应中心的共组装的肽-卟啉纤维可以用作原始的类光细菌细胞模型,以实现光捕获、能量转移和最终可持续的氢释放。
Molecular evolution, with self-organization of simple molecules towards complex functional systems, provides a new strategy for biomimetic architectonics and perspectives for understanding the complex processes of life. However, there remain many challenges to fabrication of systems comprising different types of units, which interact with one another to perform desired functions. Challenges arise from a lack of stability, dynamic properties, and functionalities that reconcile with a given environment. A co-assembling fiber system composed of simple peptide and porphyrin is presented. This material is considered a prebiotic assembly of molecules that can be rather stable and flexibly self-functionalized with the assistance of visible light in a "prebiotic soup"; acidic (pH 2), hot (70 degrees C), and mineral-containing (Na+, Ti4+, Pt2+, and so forth) water. The co-assembled peptide-porphyrin fiber, with self-mineralized reaction centers, may serve as a primitive photobacteria-like cellular model to achieve light harvesting, energy transfer, and ultimately sustainable hydrogen evolution.
