CrLOV2
Protein DomainCrLOV2 is the LOV2 photosensory domain from Chlamydomonas reinhardtii phototropin that has been mechanistically mapped for FMN photoadduct formation. It supports both the canonical triplet-state LOV photoreaction and a direct adduct-forming pathway from the initially excited S1 singlet state, with proton or hydrogen transfer coupling implicated in the direct channel.
