Abstract

This chapter focuses on the design and applications of protein-polymer conjugates. Protein-polymer conjugates are synthesized by conjugating a polymer chain or many polymer chains onto a protein. The site of conjugation, protein, polymer, and stoichiometry are important criteria when designing a protein-polymer conjugate. The important structural aspects and functions of proteins, such as hierarchical structure and activity, are discussed. The various methods of site-specific conjugation, “grafting to”, “grafting from” and cofactor reconstitution, are included along the pros and cons of each method. Conjugates synthesized by random conjugation are also discussed. The specific reactions used for protein attachment are not included, as numerous synthetic reviews exist; however, a broad overview of the field is presented. Novel conjugate structures can be synthesized by attaching synthetic peptide sequences onto polymers. In addition to design considerations, the range of applications from drug delivery systems to biosensors are discussed. This chapter aims to aid in furthering the knowledge and growth of the synergistic combination of proteins and polymers.
