Cystine-knot motif
WebAug 4, 2024 · Cyclotides are not directly amenable to sequencing because of their CCK motif and absence of free C- and N-terminus. Therefore, reduction and alkylation of disulfide bonds and linearization of the peptide backbone were necessary before determining their amino acid sequences in the present study.
