Many millions of peptides self-assemble to form a gigadalton peptide fibre 2 KIAALKQKIASLKQEIDALEYENDALEQ synthetic construct 0.00317

Peptides were synthesized by microwave-assisted solid-phase peptide synthesis using standard HBTU activation. They heterodimerize to form offset dimeric coiled coils with complementary sticky ends that assemble to form extended coiled coil fibrils. These fibrils pack laterally to generate large proteinaceous fibres on average 82 nm in diameter and 42 micrometers in length.
