The arabidopsis thaliana HY4 gene encodes CRY1, a 75-kilodalton flavoprotein mediating blue light-dependent regulation of seedling development. CRY1 is demonstrated here to noncovalently bind stoichiometric amounts of flavin adenine dinucleotide (FAD). The redox properties of FAD bound by CRY1 include an unexpected stability of the neutral radical(More)
Human sulfide:quinone oxidoreductase (SQOR) catalyzes the conversion of H2S to thiosulfate, the first step in mammalian H2S metabolism. SQOR's inability to produce the glutathione persulfide (GSS(-)) substrate for sulfur dioxygenase (SDO) suggested that a thiosulfate:glutathione sulfurtransferase (TST) was required to provide the missing link between the(More)
