Avena sativa phototropin LOV2 domain
Protein DomainThe Avena sativa phototropin LOV2 domain is a recombinant blue-light-sensing protein domain that binds flavin mononucleotide (FMN) and undergoes a reversible light-triggered conformational change. Blue light induces formation of a cysteinyl-FMN adduct, and the adduct spontaneously reverses in the dark, enabling optomechanical signal transduction.
