The SFB members Dr. Victor A. Lórenz-Fonfría and Prof. Joachim Heberle from project B3 have published an article and video demonstrating "Proton Transfer and Protein Conformation Dynamics in Photosensitive Proteins by Time-resolved Step-scan Fourier-transform Infrared Spectroscopy" (1). The video is openly accessible on the website of JoVE, the Journal of Visualized Experiments, which is is the world's first peer reviewed scientific video journal.

In their video, Lórenz-Fonfría and Heberle demonstrate "key steps of protein function, in particular backbone conformational changes and proton transfer reactions, [which] often take place in the microsecond to millisecond time scale. These dynamical processes can be studied by time-resolved step-scan Fourier-transform infrared spectroscopy, in particular for proteins whose function is triggered by light." (1)
