Synthetic genes for avian pancreatic polypeptide (aPP) and PPBR4 protein were successfully expressed on M13 bacteriophage surfaces. These engineered phages offer a platform for optimizing novel miniature proteins derived from aPP.

Area of Science:

  • Molecular biology
  • Protein engineering
  • Biotechnology

Background:

  • Avian pancreatic polypeptide (aPP) is a peptide hormone with potential applications in protein engineering.
  • Miniature proteins offer advantages in stability and functionality.
  • Previous protein grafting procedures have been established for modifying aPP.

Purpose of the Study:

  • To develop a novel method for expressing synthetic genes on bacteriophage surfaces.
  • To create engineered M13 bacteriophage displaying avian pancreatic polypeptide (aPP) and PPBR4.
  • To establish a platform for optimizing miniature proteins based on aPP.

Main Methods:

  • Gene synthesis of avian pancreatic polypeptide (aPP) and PPBR4.
  • Cloning of synthetic genes into expression vectors for M13 bacteriophage.
