Proteins have the potential to replace synthetic small molecule drugs due to their specificity and selectivity in their activity. However, if administered in their native form, they can aggregate leading to immunogenicity or get cleared by renal and reticuloendothelial system which ultimately hampers their efficacy as therapeutic agents. Thus, the formulation in which proteins are administered plays a key role in retaining their biological activity and lowering immunogenicity while minimizing the dosage requirements. Enzyme-wrapping, using synthetic polymers, is a strategy employed to provide enzymes with lower immunogenicity, longer circulation times and better targeting capabilities. Protein-polymer complexation methods, involving covalent, non-covalent and electrostatic interactions, that can provide means to develop formulations for retaining enzyme stability are discussed in this chapter.
