Although widely used in the detection and characterization of protein-protein interactions, Y2H screening has been under-used for the engineering of new optogenetic tools or the improvement of existing tools. Here we explore the feasibility of using Y2H selection and screening to evaluate libraries of photoswitchable protein-protein interactions. We targeted the interaction between circularly permuted photoactive yellow protein (cPYP) and its binding partner binder of PYP dark-state (BoPD) by mutating a set of four surface residues of cPYP that contribute t
