This course will focus on enzymatic mechanisms and the chemistry involved: typical amino acids in enzymatic mechanisms and the type of chemistry they catalyze. Fundamental chemical steps involved in enzymatic mechanisms will be discussed (e.g. nucleophilic attack, proton transfer etc.), alongside basic concepts such as ‘transition state stabilization’.
Students will become familiar with:
- Types of enzyme classes (hydrolases, transferases, etc.)
- Types of reaction mechanisms (addition, elimination, isomerisation, etc.)
- Types of chemical steps in enzymatic reactions (nucleophilic attack, acid/base catalysis, etc.)
Main focus will be on understanding how certain types of amino acids and their placement can promote chemical reactions. Simple concepts of thermodynamics (barrier, reaction energy) will be discussed briefly.
There will be a computational part where students will use a (free) software to look at the active sites of selected enzymes and see how the catalytic residues are placed in 3D, illustrating how placement is important for efficient catalysis. The course will contain several case studies of relevant enzyme types. At the end of the course, the students will conduct a literature study and write an assignment on an enzyme of choice.

The course is given intensively over 1 week, followed by own project work.
The course will involve lectures based on the textbook, seminars with relevant exercises, including computer exercises for visualizing enzymatic active sites, and one afternoon in the lab for demonstrating enzymatic reactions in practice.
- Minimum 80% attendance
- Approved project work
