Protein Structure Analysis


This course covers data resources and analytical approaches for the discovery and interpretation of biomacromolecular structures.

Day 1 focuses on public repositories of structural data (Protein Data Bank and Electron Microscopy Data Bank) and resources for protein analysis and classification (Pfam, InterPro and HMMER)

Day 2 covers how to retrieve information about the structure and function of your protein sequence using CATH, principles of modern state-of-the-art protein modelling with Phyre2 and methods for predicting the effects of mutations on protein structure and function using the SAAP family of tools.

Audience and Prerequisites

  • Understanding of the basics of protein structure is expected.
  • Graduate students, Postdocs and Staff members from the University of Cambridge, Affiliated Institutions and other external Institutions or individuals.


Syllabus, Tools and Resources

During this course you will learn about:

  • How to find, visualise and interpret macromolecular structures in the PDB and EMDB using our online tools.
  • How CATH provides information on protein sequence, structure and function
  • How protein modelling works, how to model your own proteins and when to trust the results.
  • An overview of approaches to mutation effect prediction and their performance and limitations.


Learning Objectives

After this course you should be able to:

  • Discover protein and nucleic acid structures related to your area of work and understand how this information could be used to further your own research
  • Scan a protein sequence against CATH and interpret the significance and biological meaning of results
  • Create your own protein models and analyse their features and assess their reliability
  • Use mutation prediction methods and evaluate their performance.
