Mapping the interactions between flavodoxin and its physiological partners flavodoxin reductase and cobalamin-dependent methionine synthase.
Flavodoxins are electron-transfer proteins that contain the prosthetic group flavin mononucleotide. In Escherichia coli, flavodoxin is reduced by the FAD-containing protein NADPH:ferredoxin (flavodoxin) oxidoreductase; flavodoxins serve as electron donors in the reductive activation of anaerobic ribonucleotide reductase, biotin synthase, pyruvate formate lyase, and cobalamin-dependent methionin...
متن کاملFlavodoxin and NADPH-flavodoxin reductase from Escherichia coli support bovine cytochrome P450c17 hydroxylase activities.
Two soluble flavoproteins, purified from Escherichia coli cytosol and identified as flavodoxin and NADPH-flavodoxin (ferredoxin) reductase (flavodoxin reductase), have been found in combination to support the 17 alpha-hydroxylase activities of heterologously expressed bovine 17 alpha-hydroxylase cytochrome P450 (P450c17). Physical characteristics of the two flavoproteins including absorbance sp...
متن کاملCrystallisation of the flavodoxin from Megasphaera eldenii .
Flavodoxins are small flavoproteins (M, 15000-22000), that have been found in several strains of bacteria and algae [ I ] The protein contains one molecule of non-covalently bound FMN and hnctions biochemically as a one-electron carrier between the semiquinone and hlly reduced forms. Under iron-deficient conditions the protein is produced by Megasphaera elsdenii to replace the iron-sulphur prot...

متن کاملCrystallographic characterization of flavodoxin from Anacystis nidulans.
Flavodoxin isolated from the blue-green alga, Anmyatis nidulana, crystallizes from ammonium sulfate in space group P2,2,2,, wwith a = 67.08 A, b = 69.24 A and c = 45.55 A. The diffraction patterns extend to a resolution of at least 1.8 A. Reduction of the flavin mononucleotide in the crystalline protein, to either the semi-quinone or fully reduced (hydroquinone) state, results in minimal change...
