C4 BIOCAT – Enzyme kinetics, course code BIO910 at UiS

Key information

Dates: Desember, 2020

Place: Måltidets Hus, the Centre for Organelle Research, University of Stavanger

Course responsible: Prof. Peter Ruoff, University of Stavanger, Stavanger, Norway.

Course code: BIO910 at UiS

Exam: pass/not pass

Credits: 5 ECTS  

Registration: Deadline 03.11.2018,  register both to biocat@uit.no and to carolina.hara@uis.no in order to apply for a guest student status at UiS, course code BIO910



The course is aimed at PhD students with interests in enzyme kinetics and mathematical modelling of enzymatic/metabolic reactions. The course covers traditional enzyme kinetics topics, but also newer concepts from signal transduction kinetics and robust control (integral feedback) are included. Dependent on the students’ backgrounds and their thesis-work some of the topics may be given in more depth.


After the lectures have been completed and approved, students work on an essay with a self-chosen (needs to be approved) topic or a given topic related to enzyme kinetics.

Course evaluation

Exam and evaluation (including the essay) 

Pass/not pass

Work requirement

After the lectures have been completed and approved, students work on an essay with a self-chosen (needs to be approved) topic or on a given topic related to enzyme kinetics. After the course the student can keep fully working versions of the simulation software they used during the course.

Minimum 80% attendance and approved project work/report.



Lectures are based on: Athel Cornish-Bowden, Fundamentals of Enzyme Kinetics, Fourth Edition, Wiley-Blackwell and handouts/papers. Please bring with you a laptop computer.

Learning outcome

The candidate will be able to design and conduct enzyme kinetic experiments, has knowledge and general competence about the different classes of enzyme mechanisms, including inhibition, activation, and allosteric mechanisms. The candidate learns experimental and computational skills, methods how to extract rate parameters from experiments, estimate their significance and sensitivities, how to set up reaction kinetic models and how to perform simulation calculations.
