The photochemistry of the light-, oxygen-, and voltage sensitive domains in the algal blue light receptor phot
The photochemistry of the light-, oxygen-, and voltage sensitive domains in the algal blue light receptor phot
Phot proteins are blue light photoreceptors in plants and algae that mainly regulate photomovement responses. They contain two light-, oxygen-, and voltage-sensitive (LOV) domains and a serine/threonine kinase domain. Both LOV domains noncovalently bind a flavin mononucleotide (FMN) as chromophore....

Phot proteins are blue light photoreceptors in plants and algae that mainly regulate photomovement responses. They contain two light-, oxygen-, and voltage-sensitive (LOV) domains and a serine/threonine kinase domain. Both LOV domains noncovalently bind a flavin mononucleotide (FMN) as chromophore. Upon blue light illumination, the LOV domains undergo a photocycle, transiently forming a covalent adduct of the FMN moiety with a nearby cysteine residue. The presence of two light-sensitive domains in the photoreceptor raises the question about the differences in properties and function between LOV1 and LOV2. As a model system, the photocycles of the LOV1 and LOV2 domains from phot of the green alga Chlamydomonas reinhardtii have been studied in detail, both separately and in a tandem construct. Here we give an overview about the results on the individual behavior of the domains and their interaction. Furthermore, the current status in the understanding of the role of LOV1 in phot in general is presented. |
