Irreversible photoreduction of flavin in a mutated Phot-LOV1 domain.

Biochemistry - 26 Aug 2003

Abstract excerpt

Phot photoreceptors make up an important protein family regulating biological processes in response to blue light. 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). Upon absorption of blue light, the LOV domains undergo a photocycle, transiently forming a covalent adduct of a cysteine residue...
