Abstract

The nonequilibrium relaxation of a series of, in part, very different photoactive proteins is compared, ranging over up to eleven decades in time. The series comprises various PDZ domains and MCL 1/peptide complexes with artificial azobenzene photoswitches, as well as two different cyanobacteriochromes (Slr-g3 and TePixJ). In either case, an embedded chromophore photoisomerizes after electronic excitation on an ultrafast femtosecond to picosecond timescale, initially perturbing the structure of the protein directly around the chromoph
