Researchers explored protein backbone modifications by replacing amide bonds with ester bonds. This review examines structural, thermodynamic, and functional impacts across nine protein systems, aiding understanding of protein folding and function.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Protein Engineering

Background:

  • Advancements in chemical and biological techniques enable backbone modifications in proteins.
  • Site-directed mutagenesis is crucial for investigating the polypeptide backbone's role in protein folding and function.

Purpose of the Study:

  • To review studies on ester-bond containing protein analogues.
  • To discuss the consequences of backbone amide-to-ester bond mutations.

Main Methods:

  • Review of existing literature on ester-bond containing protein analogues.
  • Analysis of studies involving site-directed mutagenesis.

Main Results:

  • Examined 25 ester-bond analogues across nine protein systems.
