Recombinant Expression of Cyclotides Using Expressed Protein Ligation.

ABSTRACT: Cyclotides are naturally occurring microproteins (≈30 residues long) present in several families of plants. All cyclotides share a unique head-to-tail circular knotted topology containing three disulfide bridges forming a cystine knot topology. Cyclotides possess high stability to chemical, physical, and biological degradation and have been reported to cross cellular membranes. In addition, naturally occurring and engineered cyclotides have shown to possess various pharmacologically relevant activities. These unique features make the cyclotide scaffold an excellent tool for the design of novel peptide-based therapeutics by using molecular evolution and/or peptide epitope grafting techniques. In this chapter, we provide protocols to recombinantly produce a natively folded cyclotide making u
