Course content

Overview of protein structure, experimental structure determination and structure analysis, calculation of RMSD and structure superposition, fold classification (CATH, SCOP, new methods), inference of function from structure, 1D prediction (secondary structure, solvent exposure, neural networks, HMMSTR) & sampling of protein conformations (TorusDBN, directional statistics), homology modelling & the loop closure problem, knowledge based energy functions, de novo prediction methods (ROSETTA, LINUS). RNA 2D and 3D structure prediction. Python based practicals using Biopython's Bio.PDB module.

Type of assessment

Written assignment, 54 hours
The exam will consist of a take home programming task, that is, the development of a program that solves a specific structural bioinformatics problem. The program needs to be implemented in Phython using Bio.PDB (Biophython´s structural toolkit). You will have time for the take home assignment in week 3 and 4.

Marking scale

7-point grading scale

Criteria for exam assessment

To obtain the grade 12:

  • The student must be able to explain the motivation, biological relevance and use of the methods covered in the course.
  • The student must be able to present and explain the mathematical and algorithmic details of the methods covered in the course.
  • The student must be able to suggest which methods and programs to apply for a given biological problem, and to point out problems and difficulties relating to such applications.
  • The student must be able to implement standard algorithms to solve standard structural bioinformatics problems in Python and Bio.PDB, and to design and implement novel, related algorithms to solve related problems.
