from collagen sequences, were designed, mainly by Greg
Fields and his group. The challenge was to synthesize structures,
which would be stable enough to remain in triplehelical
conformation in the conditions of assays.
Different approaches have been described. A solid-phase
synthesis was first developed, featuring a C-terminal covalent
branch and incorporating specific sequences between this
branch and a N-terminal (Gly-Pro-Hyp)n domain
