Furthermore, the de novo design of antifreeze peptides has explored various structural motifs. Researchers have successfully engineered peptides with specific secondary structures, such as $\alpha$-helical peptides, to tune their antifreeze activity作者：X Zhang·2023·被引用次数：23—In this work,three low immunogenic antifreeze peptidesare developed based on the functional motif of the Tenebrio molitor antifreeze protein (TmAFP).. The design and synthesis of peptides that exhibit ice-binding and antifreeze activity often involves creating structures like single-ring or double-ring cyclic peptides, or even dendrimeric polypeptides. For example, a strategy for the design and synthesis of peptides that exhibit ice-binding and antifreeze activity involves the creation of 9-14 amino acid polypeptides, into which four semi-bound amino acids are inserted. These semi-bound amino acids can then randomly pair up to form single or double rings. By introducing random mutations into other amino acids within the polypeptide chain, a library of approximately 2x10¹⁰ different sequences can be generated for screeningKing Lab | Publications - University of Washington.
