Abstract

Artificial virus-like capsids decorated with ribonuclease S (RNase S) on their exterior were constructed by the self-assembly of β-annulus-S-peptide and the interaction between S-peptide moiety and S-protein. The β-annulus-S-peptide was synthesized by native chemical ligation of β-annulus-SBz peptide with Cys-containing S-peptide that self-assembled into artificial virus-like capsids of approximately 47 nm in size. Reconstruction of RNase S on the artificial virus-like capsids afforded spherical assembly attached small spheres on the surface, which retained ribonuclease activity.
