High‐resolution crystal structures reveal a mixture of conformers of the Gly61‐Asp62 peptide bond in an oxidized flavodoxin from Bacillus cereus

open access: greenProtein Science, 2018
Flavodoxins (Flds) are small proteins that shuttle electrons in a range of reactions in microorganisms. Flds contain a redox‐active cofactor, a flavin mononucleotide (FMN), and it is well established that when Flds are reduced by one electron, a peptide ...

Crystal structure of AdoMet radical enzyme 7‐carboxy‐7‐deazaguanine synthase from Escherichia coli suggests how modifications near [4Fe–4S] cluster engender flavodoxin specificity [PDF]

open access: bronzeProtein Science, 2018
7‐Carboxy‐7‐deazaguanine synthase, QueE, catalyzes the radical mediated ring contraction of 6‐carboxy‐5,6,7,8‐tetrahydropterin, forming the characteristic pyrrolopyrimidine core of all 7‐deazaguanine natural products. QueE is a member of the S‐adenosyl‐L‐

Substitution of CH<sub>3</sub> by CH<sub>2</sub>F in 2-Methylerythritol Cyclodiphosphate Triggers Potent Inhibition of IspG with Concomitant Fluoride Ion Expulsion. [PDF]

open access: yesChemistry
The fluoromethyl analogue of MEcPP was identified as a very potent inhibitor of the oxygen‐sensitive [4Fe‐4S] metalloenzyme IspG. In the course of the IspG‐catalyzed transformation, this novel compound undergoes fluoride elimination, offering additional evidence for the involvement of a carbanionic intermediate in the mechanism of this enzyme ...

Suppression of Reactive Oxygen Species Accumulation in Chloroplasts Prevents Leaf Damage but Not Growth Arrest in Salt-Stressed Tobacco Plants. [PDF]

open access: yesPLoS ONE, 2016
Crop yield reduction due to salinity is a growing agronomical concern in many regions. Increased production of reactive oxygen species (ROS) in plant cells accompanies many abiotic stresses including salinity, acting as toxic and signaling molecules ...

Divergent functions of two clades of flavodoxin in diatoms mitigate oxidative stress and iron limitation

open access: yesbioRxiv, 2022
Phytoplankton rely on diverse mechanisms to adapt to the decreased iron bioavailability and oxidative stress-inducing conditions of today’s oxygenated oceans, including replacement of the iron-requiring ferredoxin electron shuttle protein with a less ...

The Candida albicans ζ-crystallin homolog Zta1 promotes resistance to oxidative stress

open access: yesmSphere, 2023
The fungal pathogen Candida albicans is capable of causing lethal infections in humans. Its pathogenic potential is due in part to the ability to resist various stress conditions in the host, including oxidative stress.
