Flavodoxin from Wolinella succinogenes

Archives of Microbiology, 1996
A monomeric flavoprotein (18.8 kDa) was isolated from the soluble cell fraction of Wolinella succinogenes and was identified as a flavodoxin based on its N-terminal sequence, FMN content, and redox properties. The midpoint potentials of the flavodoxin (Fld) at pH 7.

Structure-function relations in flavodoxins

Molecular and Cellular Biochemistry, 1980
Flavodoxins are low molecular weight, FMN containing, proteins which function as electron transfer agents in a variety of microbial metabolic processes, including nitrogen fixation. Utilizing structural information obtained from x-ray crystal analysis, it has been possible to derive some new and important insights into the relationships which exist ...

Encapsulation of Flavodoxin in Reverse Micelles

Biochemical and Biophysical Research Communications, 1997
The regulation of the properties of Desulfovibrio gigas flavodoxin in AOT/water/iso-octane micellar system was studied. UV-visible spectroscopic studies have shown that photoreduction of flavodoxin in the presence of EDTA leads to hydroquinone formation through the intermediate semiquinone.

Time-resolved tryptophan fluorescence in flavodoxins

Journal of Fluorescence, 1995
The time-resolved fluorescence characteristics of tryptophan in flavodoxins isolated from the bacteriaDesulfovibrio gigas, Desulfovibrio vulgaris, Clostridium beijerinckii, andMegasphaera elsdenii were examined. The fluorescence decays were recorded using pulsed synchrotron radiation as the excitation source and time-correlated single-photon counting ...

Flavodoxin and rubredoxin from Desulphovibrio salexigens

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1980
A flavodoxin and a rubredoxin have been isolated from the sulfate-reducing bacterium Desulphovibrio salexigens (strain British Guiana, NICB 8403). Their amino acid composition and spectral characteristics did not differ markedly from the homologous proteins presented in other Desulphovibrio spp.

Electron-transfer reactions between flavodoxin semiquinone and c-type cytochromes: comparisons between various flavodoxins

Biochemistry, 1986
As an extension of previous work from this laboratory using Clostridium pasteurianum flavodoxin [Tollin, G., Cheddar, G., Watkins, J. A., Meyer, T. E., & Cusanovich, M. A. (1984) Biochemistry 23, 6345-6349], we have measured the rate constants as a function of ionic strength for electron transfer from the semiquinones of Clostridium MP, Anacystis ...

Structure of cyanobacterial photosystem I-IsiA-flavodoxin supercomplex

, 2020
Under iron-deficiency stress, which occurs frequently in natural aquatic environments, cyanobacteria reduce the amount of iron-enriched proteins, including photosystem I (PSI) and ferredoxin (Fd), and upregulate the expression of iron-stress-induced ...

Crystallisation of the flavodoxin from Megasphaera eldenii

Biochemical Society Transactions, 1996
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.

Stress‐inducible flavodoxin from photosynthetic microorganisms. The mystery of flavodoxin loss from the plant genome

IUBMB Life, 2007
AbstractFlavodoxins (Flds) are mobile electron carriers containing flavin mononucleotide as the prosthetic group. They are isofunctional with the ubiquitous electron shuttle ferredoxin (Fd), mediating essentially the same redox processes among a promiscuous lot of donors and acceptors.

Dimerization of Azotobacter vinelandii flavodoxin (azotoflavin)

Archives of Biochemistry and Biophysics, 1975
Abstract Molecular weight determinations by gel filtration of Azotobacter vinelandii flavodoxin (azotoflavin) which had been stored aerobically for various periods of time indicated that this flavoprotein electron carrier could exist in the monomeric ( M r = 23,000) or dimeric ( M r = 46,000) form.
