Abstract

S-layers are produced by the self assembly of proteinaceous subunits on the surfaces of prokaryotes, so that planar, monomolecular-thick crystalline lattices are formed. Some archaeal and eubacterial S-layer proteins are glycosylated. These lattices typically have center-to-center spacings of less than 25 nm, which makes them attractive for biomimetic or nanotechnological applications.

摘要

S层是由蛋白质亚基在原核生物表面自组装产生的，从而形成平面的、单分子厚度的晶格。一些古细菌和真细菌的S层蛋白是糖基化的。这些晶格的中心间距通常小于25纳米，这使得它们在仿生或纳米技术应用中具有吸引力。
