WebApr 10, 2024 · The covalent bond between the LOV domain of PHOT and the FMN chromophore is spontaneously degraded in the dark, inactivating PHOT. In the liverwort, this inactivation process is slowed by cold temperatures, enabling cold-avoidance responses. (E) RUP-mediated dimerization of UVR8 promoted by high temperatures. A FMN-binding fluorescent protein (FbFP), also known as a LOV-based fluorescent protein, is a small, oxygen-independent fluorescent protein that binds flavin mononucleotide (FMN) as a chromophore. They were developed from blue-light receptors (so called LOV-domains) found in plants and various bacteria. They complement the GFP-derivatives and –hom…
