Fusion peptidesreviews Fusion peptides are a fascinating class of molecules playing crucial roles in biological processes, particularly in viral entry and cellular membrane interactions. These short chains of amino acids, typically ranging from 16 to 30 residues, are characterized by their predominantly hydrophobic sequences, often enriched with amino acids like alanine, glycine, and phenylalanine. Their primary function is to facilitate the fusion of biological membranes, a process essential for various cellular activities and viral replication.

The Science Behind Fusion Peptides

At their core, fusion peptides are constituent parts of viral fusion proteins作者：A Santamaria·2022·被引用次数：59—A fusion peptide present at the N-terminal region of class I viral fusion proteinsis believed to initiate viral and cell membrane interactions.... These viral proteins are instrumental in the initial stages of infection, enabling the virus to merge its envelope with the host cell membrane. A fusion peptide is usually a prominent hydrophobic segment of viral fusion proteins that is exposed during the fusion process. Research, such as studies on SARS-CoV-2 fusion peptides, highlights their critical role in initiating viral and cell membrane interactions. These peptides are believed to insert into the target membrane, destabilizing its structure and promoting the merging of lipid bilayers.

The mechanism by which fusion peptides achieve this is complex and has been a subject of extensive scientific inquiry. Some studies suggest that these peptides can change membrane curvature and alter the state of hydration of membrane surfaces. Other research indicates that fusion peptides can generate opposing curvature stresses, thereby lowering the free energy barrier required for membrane fusionMachine and deep learning to predict viral fusion peptides. For instance, the influenza virus utilizes its amphipathic fusion peptide (FP), spearheaded by its spike protein, to initiate infection. Investigations into two modes of fusogenic action for influenza virus fusion peptide reveal that these peptides can adopt different conformations to facilitate membrane merging.Identification and Characteristics of Fusion Peptides ...
