The bacteriophytochrome DrBphP from Deinococcus radiodurans shows high sequence homology to the histidine kinase Agp1 from Agrobacterium fabrum but lacks kinase activity. Here, the authors structurally and biochemically analyse DrBphP and Agp1, showing that DrBphP is a light-activatable phosphatase.
