Frontiers in Microbiology, 2018 Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more ...

Electrochemical and structural characterization of Azotobacter vinelandii flavodoxin II [PDF]
Protein Science, 2017 Azotobacter vinelandii flavodoxin II serves as a physiological reductant of nitrogenase, the enzyme system mediating biological nitrogen fixation. Wildtype A. vinelandii flavodoxin II was electrochemically and crystallographically characterized to better

Cofactor binding protects flavodoxin against oxidative stress. [PDF]
PLoS ONE, 2012 In organisms, various protective mechanisms against oxidative damaging of proteins exist. Here, we show that cofactor binding is among these mechanisms, because flavin mononucleotide (FMN) protects Azotobacter vinelandii flavodoxin against hydrogen ...

Structure and function of an unusual flavodoxin from the domain Archaea
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance A flavodoxin from the domain Archaea has been characterized. It is the first of any flavodoxin shown to stabilize an anionic semiquinone, providing a platform for understanding how the protein environment modulates the reduction potentials ...

Streptococcus pneumoniae TIGR4 Flavodoxin: Structural and Biophysical Characterization of a Novel Drug Target. [PDF]
PLoS ONE, 2016 Streptococcus pneumoniae (Sp) strain TIGR4 is a virulent, encapsulated serotype that causes bacteremia, otitis media, meningitis and pneumonia. Increased bacterial resistance and limited efficacy of the available vaccine to some serotypes complicate the ...
