WebbPhoCl protein was engineered by Campbell group in 2013 ( Zhang et al., 2024 ). Upon the illumination of violet light (~400 nm), the chromophore undergoes a β-elimination reaction, leading to the cleavage of the polypeptide backbone. The two fragments of the protein then spontaneously dissociate and become unstructured.

WebbThe first generation PhoCl (PhoCl1) exhibited a relative slow rate of dissociation, potentially limiting its utilities for optogenetic control of cell physiology. In this work, we report the X-ray crystal structures of the PhoCl1 green state, red state, and cleaved empty barrel. Using structure-guided engineering and directed evolution, we have ... WebbSeveral different screening systems based on bimolecular fluorescence complementation and FRET were developed to screen directly for the photoinduced dissociation of a photocleavable protein (PhoCl) developed in our lab. A second photocleavable protein called SplitOr was created from PSmOrange2.
