Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Are cryptic host species also cryptic to parasites? Host specificity and geographical distribution of acanthocephalan parasites infecting freshwater Gammarus [PDF]

, 2011
Many parasites infect multiple host species. In coevolving host–parasite interactions, theory predicts that parasites should be adapted to locally common hosts, which could lead to regional shifts in host preferences.

Disentangling the identity of Lebertia porosa Thor, 1900 using integrative taxonomy (Acari: Hydrachnidia)

European Journal of Taxonomy, 2022
Initial analyses of DNA barcode data from Norwegian populations attributed to the water mite Lebertia porosa Thor, 1900 revealed large genetic divergence and potentially cryptic species-level diversity.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Double Reduction of Ph3B to a Dianionic Borane With a Powerful SrI Intermediate

Angewandte Chemie, EarlyView.
Although dianionic boranes follow the octet rule and are isoelectronic to carbanions or amines, the high electron density combined with the electropositive nature of the B center make them highly unstable species. In this study, we present synthesis and full characterization of a complex in which Ph3B2− is sandwiched between two Sr2+ ions and describe ...

Cryptic biodiversity and phylogeographic patterns of Seychellois Ligia isopods [PDF]

PeerJ, 2017
Ligia isopods are conspicuous inhabitants of rocky intertidal habitats exhibiting several biological traits that severely limit their dispersal potential.

Going viral − Virus‐targeting nanobodies for research, diagnostics and therapy

FEBS Letters, EarlyView.
The increasing prevalence of viral diseases represents a major threat for global human health. Nanobodies, small binding fragments derived from camelid heavy‐chain antibodies, offer versatile tools for viral research, diagnostics, and antiviral therapy.

Borosulfates Hosting Se42+ Ions—Crystal Structures, Chemical Bonding, Optical Spectroscopy, and Magnetism

Angewandte Chemie, EarlyView.
Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic

Cryptic species are widespread across vertebrates

Proceedings of the Royal Society B: Biological Sciences
Abstract Many species delimited by morphological data contain two or more species that are distinct based on molecular data (i.e. cryptic species). Cryptic species have important implications for ecology, evolution and conservation. For example, morphology-based species of limited conservation concern can contain cryptic species that ...

Genetic dissection of human ABCE1 in yeast reveals separable requirements for ribosome recycling and suppression of aberrant reinitiation

FEBS Open Bio, EarlyView.
Human ABCE1 cannot functionally replace its yeast ortholog. Yeast–human chimera analysis identified NBD1 as a major interspecies barrier. Genetic screening yielded hABCE1 revertants that rescue yeast viability but fail to suppress aberrant translation reinitiation in the 3′ UTR.
