An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

“Guidance but not the ultimate commandment”: Pros and Cons of Using Pivot Templates in the Audio Description Production Workflow

open access: yesJoSTrans: The Journal of Specialised Translation
The need for audio-described audiovisual content is mainly growing due to statutory accessibility required in many countries. Regrettably, despite the popular and legal demand for audio description, broadcasters and producers perceive audio description

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

A Description of the Uses of Content Analyses and Interviews in Educational/Psychological Research

open access: yesForum: Qualitative Social Research, 2000
Psychology in general, and educational psychology in particular, has traditionally adopted the methods of positivistic science; that is, it employs experimental research methodology and statistical tests of significance.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
