ESC4: Advanced kinetics approaches to unravel protein structure and function

Description of the course:

The course will be focused on the application of advanced kinetics techniques (stopped flow binding and folding experiments, FRET, T-Jump) to study protein structure and functions and to dissect several kinetics mechanisms.

Understanding the links between protein structure and function is a critical task of Molecular Biology. Such a goal has critical scientific implications, spanning from basic research to practical applications such as drug discovery and the development of new therapies. In this perspective, advanced kinetic approaches have emerged as powerful tools for unravelling these features: the ESC4 course “Advanced Kinetics Approaches to Unravel Protein Structure and Function” covers a range of kinetic and spectroscopic techniques that may help scientist to unveil the subtle links between protein structure and function. These techniques include stopped-flow, T-jump and Forster resonance energy transfer (FRET) experiments.

In a stopped-flow apparatus, two solutions are rapidly mixed and subsequently stopped, allowing for the recording of spectroscopic signal changes over time. Optical signals typically include variations of absorbance, fluorescence, and/or circular dichroism. The dead-time of a stopped flow is in the order of ms, such that this technique is suitable for monitoring both fast and slow reaction kinetics. On the other hand, the T-jump methodology is based on a fast discharge on a quart cuvette, which results in a fast increase in the solution temperature. By applying this method it is possible to monitor the relaxation to a new equilibrium and therefore to address the reaction kinetics. The dead time of this method is in the order of microseconds, allowing to address ultrafast reactions.

Thanks to these techniques, it is possible to dissect the kinetic mechanism involving protein-protein interactions, protein (un)folding, enzyme activity, ligand binding, and FRET. With the knowledge and skills gained from this course, scientists will be better trained to tackle the challenges in biochemical and biophysical research.

Outline of the course:

The course will start on Monday the 2^nd and end midday Wednesday the 4^th of October.

Day 1

13:00: Registration and welcome to the participants.

14:00 Introduction: MOSBRI, possibilities and perspectives

Lecture 1:       Essential kinetics in biochemistry and biophysics
Lecture 2:      Experimental methods to address time resolved reaction kinetics
Lecture 3:      Experimental characterization of folding and binding reactions

Coffee break

Lecture 4:      Steady-state analysis of complex inhibition systems
Lecture 5:      Pre steady-state analysis to dissect the mechanism of enzyme catalysis

Day 2

Practical sessions

Participant speed talks (5’ each): each participant will be required to briefly present his/her research.

Three groups will be formed for hands-on teams consisting of 3 participants. The duration of each practical session will be approximately 2 hours, so that Day 2 will be entirely devoted to the experimental part. A rotation between groups and practical courses will be organized.

Due to organizational reasons, participants are not allowed to bring their own samples.

Practical topics: Stopped flow binding and folding experiments, FRET, T-Jump

Evening of Day 2: Dinner with the participants and the tutors

Day 3

Day 3 will consist of kinetic data analysis and discussion.

~Midday: Feedback and goodbye.

Other details:

Participants will receive financial support to attend the course, including a contribution to their travel, lunch, dinners, and 2 nights of accommodation (accommodation will be booked by the organizers). Successful applicants will be informed of the eligible expenses when they receive a formal acceptance letter.
