Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones

FEBS Letters, EarlyView.
Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Potential and pH dependence of the buried interface of membrane-coated electrocatalysts [PDF]

arXiv, 2020
Semipermeable silica membranes are attractive as protective coatings for metal electrocatalysts such as platinum but their impact on the catalytic properties has not been fully understood. Here, we develop a first principles formalism to investigate how silica membranes interact with the surface of platinum metal electrocatalysts to develop a better ...

Imaging mitochondrial membrane potentials

Biophysical Journal, 1993
process remain to be elucidated. The elusiveness of this goal can be attributed, at least in part, to the absence of structural information about the mitochondrion itself at several levels of complexity. It is obvious, for example, that obtaining atomic structures of the respiratory chain protein complexes by x-ray or electron crystallography would ...

Effects of beauvericin on root cell transmembrane electric potential, electrolyte leakage and respiration of maize roots with different susceptibility to Fusarium

Plant, Soil and Environment, 2006
Effect of beauvericin on root cell transmembrane electric potential (EM), electrolyte leakage and respiration of roots were studied in two maize cultivars (Zea mays L.) with different susceptibility to this toxigenic metabolite produced by Fusarium ...

Structural and mechanistic basis for the regulation of the chloroplast signal recognition particle by (p)ppGpp

FEBS Letters, EarlyView.
LHCPs are transported to the thylakoid membrane via the (cp)SRP pathway. This process involves a transit complex of (cp)SRP43, (cp)SRP54 and LHCP, which interacts with (cp)FtsY and Alb3 at the membrane. GTP hydrolysis by (cp)SRP54 and (cp)FtsY triggers complex dissociation.

Convulsant actions of 4-aminopyridine on the guinea-pig olfactory cortex slice [PDF]

, 1982
The effects of bath-applied 4-aminopyridine on neurones and extracellular potassium and calcium concentrations were recorded in slices of guinea-pig olfactory cortex. Neurones were orthodromically activated by stimulating the lateral olfactory tract.

Fluorinated Membrane Potential Probes [PDF]

Biophysical Journal, 2011
To explore the effect of fluorination on photophysical properties of membrane potential probes, we developed synthetic methods for ANEP dyes with fluorine substitutions at the donor, bridge, and acceptor sides. Fluorination on acceptor side induces red shifts in optical spectra while on donor side it induces blue shifts.

Analyzing the effect of ion binding to the membrane-surface on regulating the light-induced transthylakoid electric potential (ΔΨm)

Frontiers in Plant Science, 2022
The transthylakoid membrane potential (ΔΨm) is essential because it can drive the ATP synthesis through the CF0–CF1 type of ATP-synthase in chloroplasts as an energetic equivalent similar to ΔpH.

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells

FEBS Letters, EarlyView.
Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

FEBS Letters, EarlyView.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.
