Sequences of trpzip and gb1 peptides
trpzip1 | SWTWEGNKWTWK | Type II' turn |
trpzip2 | SWTWENGKWTWK | Type I' turn |
trpzip3 | SWTWEpNKWTWK | Type II' turn |
gb1, 41–56 | GEWTYDDATKTFTVTE | Type I turn |
trpzip4 | GEWTWDDATKTWTWTE | gb1: Y45W, F52W, V54W |
trpzip5 | GEWTYDDATKTFTWTE | gb1: V54W |
trpzip6 | GEWTWDDATKTWTVTE | gb1: Y45W, F52W |
All peptides were synthesized as C-terminal amides; p ≡ d-proline. Residue numbers for the gb1 peptide correspond to those of the parent 56-residue B1 domain.
