Interaction of bacterial luciferase with 8-substituted flavin mononucleotide derivatives.
Bacterial luciferase catalyzes the emission of visible light from the reaction of reduced flavin, molecular oxygen, and an n-alkyl aldehyde. The mechanism of the reaction was probed by measuring the electronic effects of various substituents at the 8-position of the flavin ring system. Substituent effects were obtained for CH3-, Cl-, CH3O-, CH3S-, F-, and H- on the rate of formation and decay o...
متن کاملFlavin mononucleotide: the coenzyme of reduced diphosphopyridine nucleotide dehydrogenase.
From the particulate reduced nicotinamide adenine dinucleotide (DPNH) oxidase of beef heart, Mackler (3) has obtained a soluble DPNH dehydrogenase which was estimated to be approximately 90 to 95% homogenous when examined electrophoretically.l Similarly, when the enzyme was chromatographed on diethylaminoethyl cellulose with phosphate buffer, pH 7.5, in a gradient elution method (0.001 M to 0.0...
متن کاملFlavin Mononucleotide: the Acid-extractable Flavin of the Dpnh-coenzyme Q Reductase of the Respiratory Chain.
Several D P N H dehydrogenases have been purified from heart mitochondria or heart-muscle preparationsl-L STRAUB'S enzym& has been shown by MASSEY 8 to be a form of lipoamide dehydrogenase (EC 1.6.4.3), while the relationship of the remaining preparations to the respiratory chain and to each other is obscure. The flavin extractable by acid t reatment has been reported to be FMN in some casesl, ...
متن کاملPurification of flavin mononucleotide-dependent enzymes by column chromatography on flavin phosphate cellulose compounds.
The chemical syntheses of monoand dimethyl esters of riboflavin phosphate were accomplished by allowing riboflavin to react with the appropriate monoand dimethylchlorophosphoric acids. Riboflavin monomethyl phosphate was found to be coenzymatically active with nicotinamide adenine dinucleotide phosphate-cytochrome c aporeductase, pyridoxine (or pyridoxamine) phosphate apooxidase, and glycolate ...
متن کاملStudies on the binding and function of flavin phosphates with flavin mononucleotide-dependent enzymes.
The binding and function of FMN, 3,6,7-trimethyl-9(l’-o-ribityl)isoahoxazine 5’-phosphate (3-methyl-FMN), 6,7dichloro-9-(l’-o-ribityl)isoalloxazine 5’-phosphate (6,7-dichloro-FMN), and 6,7-dimethyl-9-(5’-hydroxypentyl)isoalloxazine 5’-phosphate (5’-hydroxypentyl-FMN) has been investigated with reduced nicotinamide adenine dinucleotide phosphate dehydrogenase and NADPH cytochrome c reductase fro...
