5-deazaFMN-based Avena sativa LOV2 photoswitch
Protein DomainThe 5-deazaFMN-based Avena sativa LOV2 photoswitch is an AsLOV2 protein domain in which the native FMN chromophore is replaced by the flavin analogue 5-deazaFMN. Upon illumination, this cofactor-exchanged construct forms a thermodynamically stable adduct, and recovery to the dark-adapted state can be induced by light, enabling a repeatable photoswitching cycle.
