Phocl variant

Webb7 sep. 2024 · A topological variant of mMaple, named “PhoCl”, was reported by Zhang et al. in 2024 . To achieve the light-induced dissociation, PhoCl was engineered via circular permutation, followed with screening for variants with loss of … 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.
