Novelty Induces Behavioural And Glucocorticoid Responses In A Songbird Artificially Selected For Divergent Personalities [PDF]

open access: yes, 2017
Stress physiology is thought to contribute to individual differences in behaviour. In part this reflects the fact that canonical personality measures consist of responses to challenges, including novel objects and environments.

The [2Fe‐2S] cluster of mitochondrial outer membrane protein mitoNEET has an O2‐regulated nitric oxide access tunnel

open access: yesFEBS Letters, EarlyView.
The mitochondrial outer membrane iron–sulphur ([Fe‐S]) protein mitoNEET is a target of the type‐2 diabetes drug pioglitazone. Its unknown molecular function is linked to respiratory complex activity and mitochondrial function. We discovered that O2 protects the mitoNEET [2Fe‐2S] cluster against NO oxidation and desensitization towards reduction by H2S.

G-quadruplexes and mRNA localization [PDF]

open access: yesarXiv, 2013
G-quadruplexes represent a novelty for molecular biology. Their role inside the cell remains mysterious. We investigate a possible correlation with mRNA localization. In particular, we hypothesize that Gquadruplexes influence fluid dynamics.

Magnetic isotope effects: a potential testing ground for quantum biology [PDF]

open access: yesarXiv, 2023
One possible explanation for magnetosensing in biology, such as avian magnetoreception, is based on the spin dynamics of certain chemical reactions that involve radical pairs. Radical pairs have been suggested to also play a role in anesthesia, hyperactivity, neurogenesis, circadian clock rhythm, microtubule assembly, etc.

Oxidative Stress Detection With Escherichia Coli Harboring A katG\u27::lux Fusion [PDF]

open access: yes, 1996
A plasmid containing a transcriptional fusion of the Escherichia coli katG promoter to a truncated Vibrio fischeri lux operon (luxCDABE) was constructed. An E.

Characterization of fungal carbonyl sulfide hydrolase belonging to clade D β‐carbonic anhydrase

open access: yesFEBS Letters, EarlyView.
Here, we performed a functional analysis of the fungal enzymes belonging to clade D of the β‐class carbonic anhydrase family (β‐D‐CA). The β‐D‐CAs in the basidiomycete Gloeophyllum trabeum and the ascomycete Trichoderma harzianum showed very low activity in the hydration of CO2 but exhibited high activity in the hydrolysis of carbonyl sulfide (COS ...

Matrix Adhesion Polarizes Heart Progenitor Induction In The Invertebrate Chordate Ciona Intestinalis [PDF]

open access: yes, 2013
Cell-matrix adhesion strongly influences developmental signaling. Resulting impacts on cell migration and tissue morphogenesis are well characterized. However, the in vivo impact of adhesion on fate induction remains ambiguous.

A histidine‐rich extension of the mitochondrial F0 subunit ATP6 from the ice worm Mesenchytraeus solifugus increases ATP synthase activity in bacteria

open access: yesFEBS Letters, EarlyView.
The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

Elucidation of interface interactions between a dehydratase domain and an acyl carrier protein in cremimycin polyketide synthase

open access: yesFEBS Letters, EarlyView.
In modular polyketide synthases, the dehydratase (DH) domain catalyzes the dehydration reaction of the β‐hydroxyacyl unit attached to the cognate acyl carrier protein (ACP) domain. However, it is unclear how DH interacts with ACP during the reaction. In this study, we identified DH–ACP interface residues, providing the first detailed insights into DH ...
