Computational protein design has advanced significantly, enabling the creation of new protein structures. This research tests our understanding of protein energetics and structure by designing novel backbones and sequences.

Area of Science:

  • Computational biology
  • Protein engineering
  • Structural bioinformatics

Background:

  • Computational protein design has seen major advances over the last decade.
  • Software tools are now capable of stabilizing proteins, solubilizing membrane proteins, designing interactions, and creating novel structures.
  • A primary driver for these advancements is the rigorous testing of our fundamental understanding of protein energetics and structure.

Purpose of the Study:

  • To explore the capabilities of computational methods in de novo protein design.
  • To address the challenge of designing not only amino acid sequences but also protein backbones.
  • To develop and refine protocols for generating protein-like scaffolds and optimizing backbones concurrently with sequences.
