Cis‐nonProline peptides: Genuine occurrences and their functional roles

Protein Science, Volume 34, Issue 6, June 2025.
Abstract While cis peptides preceding proline can occur about 5% of the time, cis peptides preceding any other residue (“cis‐nonPro” peptides) are an extremely rare feature in protein structures, of considerable importance for two opposite reasons. On one hand, their genuine occurrences are mostly found at sites critical to biological function, from ...

Towards Scalable Electroenzymatic Hydrogen Production with [FeFe]‐Hydrogenase

ChemElectroChem, Volume 12, Issue 10, May 24, 2025.
The [FeFe]‐hydrogenase metalloenzyme is a promising biocatalyst for sustainable electrocatalytic hydrogen (H2) production, however important issues need to be addressed before this can happen. For future biotechnologies to be realized, the [FeFe]‐hydrogenase enzyme should be more oxygen resistant, be produced in viable quantities and ultimately ...

Systematic Literature Review Identifying Core Genera in the Gut Microbiome of Rainbow Trout (Oncorhynchus mykiss) and Species‐level Microbial Community Analysis Using Long‐Read Amplicon Sequencing

Aquaculture, Fish and Fisheries, Volume 5, Issue 2, April 2025.
ABSTRACT Rainbow trout (Oncorhynchus mykiss) is an important fish in global aquaculture. Various feed additives to suppress disease or reduce fish meal use have been studied. These manipulations influence the gut microbiome, which is considered to be linked to host health.

Effects of Algal‐Derived β‐Glucan on the Growth Performance, Intestinal Health, and Aeromonas veronii Resistance of Ricefield Eel (Monopterus albus)

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
Ricefield eel is an important economic fish in China. However, large‐scale intensive breeding has increased the incidence of diseases in eels. In this study, we conducted an 8‐week feeding trial to investigate the effects of β‐glucan on the growth performance, intestinal health, and Aeromonas veronii resistance of Monopterus albus (M. albus).

Protein Quakes in Redox Metalloenzymes: Clues to Molecular Enzyme Conductivity Triggered by Binding of Small Substrate Molecules

ChemistryOpen, Volume 13, Issue 12, December 2024.
Metalloenzyme conformational changes accompany electrocatalytic action. Two‐centre copper nitrite reductases (CuNIRs) are examples, mostly without non‐turnover voltammetry on Au(111)‐surfaces, while nitrite substrate triggers electrocatalysis, CuNIR conductivity, and enzyme structural expansion. We offer a quantum chemical rationale.

Reduction of azo dyes by desulfovibrio desulfuricans

Water Science and Technology, 2000
Azo dyes are widely used in textile finishing, and have become of concern in wastewater treatment because of their color, bio-recalcitrance, and potential toxicity to animals and humans. Thus, wastewater with azo dyes must be decolorized and furthermore mineralized in appropriate systems combining biological and chemical processes.

Acidophilic sulphate‐reducing bacteria: Diversity, ecophysiology, and applications

Environmental Microbiology Reports, Volume 16, Issue 5, October 2024.
Acidophilic sulphate‐reducing bacteria (aSRB) perform dissimilatory sulphate reduction under low pH and high metal conditions. They play key roles in the sulphur and carbon cycles in natural acidic environments, emphasized by their interactions with other microbial groups, which create an intricate ecological network. Potential applications of aSRB and
