Abstract
Recently, re-purposing of cyanobacterial photoreceptors as optogentic actuators enabled light-regulated protein expression in different host systems. These new bi-stable optogenetic tools enable interesting new applications, but their light-driven working mechanism remains largely elusive on a molecular level. Here, we study the optogenetic cyanobacteriochrome Am1-c0023g2 with isotope labeling and two dimensional infrared (2D-IR) spectroscopy. Isotope labeling allows us to isolate two site-specific carbonyl marker modes from the overw
