Overview of the five types of soluble blue-/UV-light-sensitive photosensory proteins and protein domains utilized in optogenetic applications. Typical characteristics for members of each family are listed, including chromophores, wavelength of maximum sensitivity (γmax), typical time constants for thermal reversion of photoactivated state (τoff) and molecular weight (MW) of minimal sensory fragment minus effectors.
