Although the photocycle of the photosensory core module of the Stigmatella aurantiaca bacteriophytochrome 2 (SaBphP2) has been extensively studied, its early dynamics have not been fully resolved. Here, the authors use time-resolved serial femtosecond crystallography to probe the associated picosecond events and report on the relative population of Z and E isomers after light activation.
