► 细菌 S 层蛋白作为纳米级构建模块具有巨大潜力。 ► 通过基因工程,功能域被纳入S层。 ► 重组融合蛋白具有功能并保持自组装能力。 ► 纳米生物技术应用包括传感器技术、诊断、疫苗开发和生物催化剂。结晶细菌细胞表面层(S 层)是许多细菌和古细菌最外层的细胞膜成分。 S层是由单一蛋白质或糖蛋白种类组成的单分子阵列,代表进化过程中形成的最简单的生物膜。关于 S 层的结构、化学、遗传学和组装的丰富信息揭示了纳米生物技术和仿生学的广泛应用。通过基因工程技术,可以将特定功能域整合到S层蛋白中,同时保持自组装能力。这些技术催生了新型亲和结构、微载体、酶膜、诊断装置、生物传感器、疫苗以及靶向、递送和封装系统。
► Bacterial S-layer proteins have a great potential as nanoscale building blocks. ► By genetic engineering, functional domains were incorporated into S-layers. ► Recombinant fusion proteins were functional and maintained self-assembly capability. ► Nanobiotechnological applications are sensor technology, diagnostics, vaccine development, and biocatalysts. Crystalline bacterial cell surface layers (S-layers) are the outermost cell envelope component of many bacteria and archaea. S-layers are monomolecular arrays composed of a single protein or glycoprotein species and represent the simplest biological membrane developed during evolution. The wealth of information available on the structure, chemistry, genetics and assembly of S-layers revealed a broad spectrum of applications in nanobiotechnology and biomimetics. By genetic engineering techniques, specific functional domains can be incorporated in S-layer proteins while maintaining the self-assembly capability. These techniques have led to new types of affinity structures, microcarriers, enzyme membranes, diagnostic devices, biosensors, vaccines, as well as targeting, delivery and encapsulation systems.
