I have also observed that polypeptide vesicles can increase the vesicle size through the direct incorporation of membrane peptides into the structure, which is a critical factor when dealing with complex, high-molecular-weight proteins.
From my perspective, the Vesicle Nucleating peptide (VNp) tags offer a robust solution for managing recombinant proteins that are otherwise prone to toxicity or insolubility. By sequestering these proteins within vesicles, the system creates a protective micro-environment. Furthermore, the emergence of variants like VNP6—a novel plant-derived vesicular signal peptide—indicates that this field is expanding rapidly, providing more options for specialized isolated vesicle nucleating polypeptide applications.
