Standard one- or three-letter amino acid codes are used except where Bpa indicates benzoylphenylalanine. Amino acids exchanged for Bpa or cysteine are noted in the alignment. All peptides were amidated (NH2) at the C terminus and either acetylated (Ac) or biotinylated at the N terminus. Photoactivatable (*) peptides were kept in the dark prior to UV-irradiation.
