  • Publication number: 20200261593
    Abstract: The present disclosure relates to the use of silica-forming peptides (SFPs) Volp1 and Salp1 for protein fusion tags for protein purification, silica formation and self-encapsulation, and controlled release of biomolecules. After preparing a fusion protein containing the Volp1 or Salp1 peptide at the C-terminal of the protein, the adsorption conditions for silica (SiO2) surface were optimized. As a result, a high-purity fusion protein could be purified without an additional tag for purification. The fusion protein containing the silica-forming peptide was self-encapsulated and stably immobilized in the silica matrix through reaction with a silica precursor. The Volp1 and Salp1 peptides showed stronger adsorption ability for silica than the previously known R5 peptide. Using these characteristics, a silica complex wherein two proteins are encapsulated was prepared by mixing the R5 fusion protein with the Volp1 or Salp1 fusion protein.
