摘要：
beta-Annulus peptides from tomato bushy stunt virus conjugated with DNAs (dA(20) and dT(20)) at the C-terminal were synthesized. The DNA-modified -annulus peptides self-assembled into artificial viral capsids with sizes of 45-160nm. -Potential measurements revealed that the DNAs were coated on the surface of artificial viral capsids. Fluorescence assays indicated that the DNAs on the artificial viral capsids were partially hybridized with the complementary DNAs. Moreover, the DNA-modified artificial viral capsids formed aggregates by adding complementary polynucleotides. Copyright (c) 2017 European Peptide Society and John Wiley & Sons, Ltd.
