Anabaena flavodoxin as an electron carrier from photosystem I to ferredoxin-NADP+ reductase. Role of flavodoxin residues in protein-protein interaction and electron transfer.
Biochemical and structural studies indicate that electrostatic and hydrophobic interactions are critical in the formation of optimal complexes for efficient electron transfer (ET) between ferredoxin-NADP(+) reductase (FNR) and ferredoxin (Fd). Moreover, it has been shown that several charged and hydrophobic residues on the FNR surface are also critical for the interaction with flavodoxin (Fld),...

15 صفحه اولRole of the C-terminal tyrosine of ferredoxin-nicotinamide adenine dinucleotide phosphate reductase in the electron transfer processes with its protein partners ferredoxin and flavodoxin.
The catalytic mechanism proposed for ferredoxin-NADP(+) reductase (FNR) is initiated by reduction of its flavin adenine dinucleotide (FAD) cofactor by the obligatory one-electron carriers ferredoxin (Fd) or flavodoxin (Fld) in the presence of oxidized nicotinamide adenine dinucleotide phosphate (NADP(+)). The C-terminal tyrosine of FNR, which stacks onto its flavin ring, modulates the enzyme af...
متن کاملFast Kinetic Methods with Photodiode Array Detection in the Study of the Interaction and Electron Transfer Between Flavodoxin and Ferredoxin NADP-Reductase
The primary function of Photosystem I (PSI)1 during photosynthesis is to provide reducing equivalents, in the form of NADPH, that will then be used in CO2 assimilation (Golbeck, 2006). In plants, this occurs via reduction of the soluble [2Fe-2S] Ferredoxin (Fd) by PSI. Subsequent reduction of NADP+ by Fdrd is catalysed by the FAD-dependent FerredoxinNADP+ reductase (FNR) (Eox/hq = -374 mV at pH...
متن کاملStructure-function relationships in Anabaena ferredoxin: correlations between X-ray crystal structures, reduction potentials, and rate constants of electron transfer to ferredoxin:NADP+ reductase for site-specific ferredoxin mutants.
A combination of structural, thermodynamic, and transient kinetic data on wild-type and mutant Anabaena vegetative cell ferredoxins has been used to investigate the nature of the protein-protein interactions leading to electron transfer from reduced ferredoxin to oxidized ferredoxin:NADP+ reductase (FNR). We have determined the reduction potentials of wild-type vegetative ferredoxin, heterocyst...
