Electron-Transfer Reactions of Re(CO)5:  Atom-Transfer-Concerted Mechanism vs Bimetallic Intermediate Formation

open access: yes, 2016
Flash photochemically generated Re(CO)5 reacts with halide complexes, Cu(Me4[14]-1,3,8,10-tetraeneN4)X+, Cu(Me2pyo[14]trieneN4)X+, and Ni(Me2pyo[14]trieneN4)X+ (X = Cl, Br, I) and ion pairs, [Co(bipy)33+, X-].

Flavin Electron Shuttles Dominate Extracellular Electron Transfer by Shewanella oneidensis

open access: yesmBio, 2013
Shewanella oneidensis strain MR-1 is widely studied for its ability to respire a diverse array of soluble and insoluble electron acceptors. The ability to breathe insoluble substrates is defined as extracellular electron transfer and can occur via direct

Formal Pericyclic-Coupled Electron Transfer: I. Stepwise Formal Diels-Alder Cycloaddition Enabled by Addition-Coupled Electron Transfer [PDF]

open access: yes, 2022
The formal Diels-Alder (D-A) reaction of alkenes with 1,2-diimine and related substrates is designed and studied by density functional theory (DFT), multi-reference and quasi-classical trajectory calculations in the presence of a benzoquinone-based ...

Electron Transfer in Biological Systems

open access: yesBiophysica
Electron transfer is one of the most essential processes in biological systems. Redox reactions, either directly or indirectly, drive the main ATP-synthesizing pathways, especially those relying on a chemiosmotic mechanism, and as such, they are ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Distance Dependence of Electron-Transfer Quenching in Rigid Media: A Discrete Site Model of Electron Transfer and Electron Exchange

open access: yesCHIMIA, 1994
The quenching of the luminescence of five emitters which span lifetimes of 1 ns to 10 s has been investigated in rigid media. The mechanism is in every case either electron transfer or electron exchange.

In Vitro Studies of Flemish, Dutch, and Wild-Type β-Amyloid Provide Evidence for Two-Staged Neurotoxicity

open access: yesNeurobiology of Disease, 2002
Mutations in the β-amyloid (Aβ) sequence of the amyloid precursor protein gene (APP) present with variable disease phenotypes. While patients with the Dutch APP mutation (E693Q) have predominantly hemorrhagic strokes, Flemish APP (A692G) patients develop

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Steering photoinduced electron transfer in intramolecular photocatalysts by peripheral ligand control [PDF]

open access: yes, 2023
Bridged photosensitizer-catalyst systems are promising models to study photocatalytic hydrogen evolution. However, the systems in literature are structurally diverse and therefore hard to compare.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
