S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Assessment of bacteriological quality and determination of antibiogram of bacteria isolated from water used in selected hospitals within Port Harcourt City and Obio/Akpor Local Government Area of Rivers State

UMYU Journal of Microbiology Research
Water is vital for life, and water void of bacterial contamination is vital for hospital consumption and use. This study aimed to determine the bacteriological quality and antibiogram of different water samples in some hospitals within Port Harcourt ...

A chemo‐enzymatic colorimetric cascade for detecting ethylene glycol contamination

The FEBS Journal, EarlyView.
A chemo‐enzymatic cascade is developed for ethylene glycol (EG) detection. EG is oxidized by GoADH with C1‐mediated cofactor recycling to produce glycolaldehyde (GAL). GAL subsequently reacts with purpald to generate a detectable purple chromophore.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

Constrictions and shear stress are key determinants of amyloidogenic light chain (AL) amyloidosis

The FEBS Journal, EarlyView.
In this study, we investigate how flow constrictions and shear stress trigger cardiac antibody light chain (AL) fibril formation and deposition. We mimic the mechanical forces exerted by the heart and the microvasculature network using a mini‐peristaltic pump setup and a grid‐type microchannel network, respectively.

The First Report of Cod Gill Poxvirus in Gills of Atlantic Cod (Gadus morhua L.) Suffering From Cardiorespiratory Disease

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Atlantic cod farming experiences renewed growth in Norway, and increased awareness is essential to address emerging diseases in this species. There are few reports on gill diseases in cod, and to date, no viral gill infections of cod have been documented. In this study, we collected samples from three sequential time points in summer 2023 from
