ESC6: EPR spectroscopy: metal centers and radicals for the study of proteins

Description of the course:

EPR spectroscopy is the technique of choice to study paramagnetic species in proteins. These paramagnetic species can be either endogenous (such as metals cofactors or radicals) or grafted to the protein of interest. This spectroscopy offers a wide range of applications including studies of enzyme mechanism, electron transfers, protein dynamics, structural transitions, and protein-protein interactions.

This short practical course is dedicated to beginners in EPR spectroscopy. It focuses on the use of different EPR spectrometers: from the classical ones (continuous wave, cw-EPR) to the most advanced ones (pulsed EPR, ENDOR, ELDOR). During the course we will give lectures on the first half day to introduce the basics of EPR and the most common applications in the field of molecular biophysics. Then each attendee will perform 3 different hands-on measurements in small groups (3 to 4 students). Best practices for EPR measurements including instrumental calibration, choice of the optimal parameters, high quality EPR spectra recording, and quantification will be reviewed. Some details about the analysis of EPR spectra will also be given.

Outline of the course:

The course will start midday on Monday the 15^th and end midday Thursday the 17^th of May.

Lunch including round table introduction of participants and hosts.

Afternoon of Day 1:

Lecture 1: Introduction to EPR spectroscopy: basic principles
Lecture 2: Applications of EPR spectroscopy to the study of metalloproteins
Lecture 3: Applications of EPR spectroscopy to the study of protein dynamics

Tour of the Mediterranean Institute of Microbiology (IMM) facilities (EPR, NMR, proteomics and fermentation platform)

Dinner in Marseille in the beach area

Practical sessions: Day 2 – Morning of Day 3:
Three groups will be formed for hands-on in teams of 3-4 participants.

The duration of each practical course will be 3 to 4 hours, so that Day 2 and 3 will be entirely devoted to the experimental part. A rotation between groups and practical courses will be organized.

Practical 1: Continuous-wave EPR spectroscopy at room temperature
Site-directed spin labelling and applications to protein dynamics studies

Practical 2: Continuous-wave EPR spectroscopy under cryogenic conditions
EPR spectra of different metalloproteins, identification of metal cofactors, illustration of the effect of the temperature

Practical 3: Introduction to pulsed EPR spectroscopy
Site-directed spin labelling and applications to protein dynamics studies

Evening of Day 2: Pizza party with the JSM3* team at the Mediterranean Institute of Microbiology
Midday of Day 3: Lunch, feedback and goodbye.

*JSM3 is the Junior Scientists Microbiology Meeting of Marseille

Other details:

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

The MOSBRI End user Short Course, EPR spectroscopy: metal centers and radicals for the study of proteins, was held at Laboratoire BIP, Marseille, France (EPR-MRS), in May 2023.

A MOSBRI course on “EPR spectroscopy: metal centres and radicals for the study of protein” took place in Marseille, 15^th – 17^th May 2023. Eleven participants from seven countries (Czech Republic, Germany, Hungary, Italy, Portugal, United Kingdom, Spain) attended this 2‐day course at the BIP laboratory (CNRS Aix-Marseille Université UMR7281). The main goal of this course was to explain the basics of EPR spectroscopy and to show the different approaches that can be used to study biomolecules. The programme included lectures during the first afternoon followed by three different EPR practicals performed in small groups for the remaining one and a half day. The attendees discovered the different use of EPR spectroscopy from the classical continuous wave EPR to more advanced pulsed EPR by running experiments both at room and cryogenic temperature. All the members of the EPR-MRS site contributed to make this event as interesting and convivial as possible.
