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 ...

Thioredoxin reductase from Bacillus cereus exhibits distinct reduction and NADPH‐binding properties
FEBS Open Bio, 2021 Low‐molecular‐weight (low Mr) thioredoxin reductases (TrxRs) are homodimeric NADPH‐dependent dithiol flavoenzymes that reduce thioredoxins (Trxs) or Trx‐like proteins involved in the activation networks of enzymes, such as the bacterial class Ib ...

Reduction of methemoglobin by ferredoxin and ferredoxin-NADP reductase system.
Journal of Biological Chemistry, 1981 The changes in absorption spectra between 450 and 650 nm during the reduction of methemoglobin A, (alpha 2+ beta 3+)2, and (alpha 3+ beta 2+)2 valency hybrids by the system including ferredoxin and ferredoxin-NADP reductase were studied under anaerobic conditions.

Biochemical characterization of ferredoxin-NADP+ reductase interaction with flavodoxin in Pseudomonas putida [PDF]
BMB Reports, 2012 Flavodoxin (Fld) has been demonstrated to bind to ferredoxin-NADP+ reductase A (FprA) in Pseudomonas putida. Tworesidues (Phe256, Lys259) of FprA are likely to be important forinteracting with Fld based on homology modeling.

Detoxification of superoxide without production of H2O2: antioxidant activity of superoxide reductase complexed with ferrocyanide [PDF]
proceedings of the national Academy of Sciences of the United
States of America, PNAS, 2006, pp.14750-5, 2015 The superoxide radical O(2)(-.) is a toxic by-product of oxygen metabolism. Two O(2)(-.) detoxifying enzymes have been described so far, superoxide dismutase and superoxide reductase (SOR), both forming H2O2 as a reaction product. Recently, the SOR active site, a ferrous iron in a [Fe(2+) (N-His)(4) (S-Cys)] pentacoordination, was shown to have the ...

Effect of Light on Chemical Modification of Chloroplast Ferredoxin-NADP Reductase [PDF]
Plant Physiology, 1980 Chemical modification of spinach chloroplasts by phenylglyoxal and dansyl chloride resulted in inhibition of NADP photoreduction. The rate of inactivation was higher with both reagents when modification was carried out in the light with methylviologen or phenazine methosulfate present. Uncouplers prevent the effect of light.

Transcriptomic and proteomic profiles of II YOU 838 (Oryza sativa) provide insights into heat stress tolerance in hybrid rice [PDF]
PeerJ, 2020 Heat stress is an increasing threat to rice production worldwide. To investigate the mechanisms of heat tolerance in hybrid rice and their contributions to rice heterosis, we compared the transcriptome of the hybrid rice II YOU 838 (II8) with the ...

A two-component flavin-dependent monooxygenase involved in actinorhodin biosynthesis in Streptomyces coelicolor [PDF]
The journal of biological chemistry, American Society for
Biochemistry and Molecular Biology, 2004, 279, pp.44362-9, 2015 The two-component flavin-dependent monooxygenases belong to an emerging class of enzymes involved in oxidation reactions in a number of metabolic and biosynthetic pathways in microorganisms. One component is a NAD(P)H:flavin oxidoreductase, which provides a reduced flavin to the second component, the proper monooxygenase.

Gene Expression Patterns during Light and Dark Infection of Prochlorococcus by Cyanophage. [PDF]
PLoS ONE, 2016 Cyanophage infecting the marine cyanobacteria Prochlorococcus and Synechococcus require light and host photosystem activity for optimal reproduction. Many cyanophages encode multiple photosynthetic electron transport (PET) proteins, which are presumed to

How native state topology affects the folding of Dihydrofolate Reductase and Interleukin-1beta [PDF]
, 2000 The overall structure of the transition state and intermediate ensembles experimentally observed for Dihydrofolate Reductase and Interleukin-1beta can be obtained utilizing simplified models which have almost no energetic frustration. The predictive power of these models suggest that, even for these very large proteins with completely different folding
