Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

FEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Effects of resource availability and interspecific interactions on Arctic and red foxes' winter use of ungulate carrion in the Fennoscandian low‐Arctic tundra

Ecology and Evolution
In the Arctic tundra, predators face recurrent periods of food scarcity and often turn to ungulate carcasses as an alternative food source. As important and localized resource patches, carrion promotes co‐occurrence of different individuals, and its use ...

Bacterial Diversity and Composition in the Internal Organs of Taiga Bean Goose, Greater White-Fronted Goose and Willow Ptarmigan as a New Tools in the Arctic Biomonitoring System

Diversity
Birds, fish, and marine mammals consumed by indigenous people are included in Arctic biomonitoring. However, there are still many gaps in the data on the microbiota associated with these animals.

Characterization of the thermophilic xylanase Fsa02490Xyn from the hyperthermophile Fervidibacter sacchari belonging to glycoside hydrolase family 10

FEBS Open Bio, EarlyView.
Fervidibacter sacchari is a member of the bacterial phylum Armatimonadota, only a few of which have been cultivated. It is a hyperthermophilic polysaccharide degradation specialist. We show that a secreted enzyme, Fsa02490Xyn, is an endoxylanase belonging to glycoside hydrolase family 10.

Preparation and characterization of renal cell peptides from fetal rats for their antitumor activity

FEBS Open Bio, EarlyView.
This study aimed to prepare renal cells (RCs) from fetal rats which were digested by enzymes. Candidate peptides RCPs were characterized by capillary HPLC and MS and their bioactivity was predicted using peptideranker. The predicted top 10 bioactive peptides were synthesized.
