Deep Proteomic Profiles of the Antarctic Diatom Fragilariopsis Cylindrus Under Varying Iron and Manganese Conditions

PROTEOMICS, Volume 26, Issue 5, Page 112-119, May 2026.
ABSTRACT Fragilariopsis cylindrus is a key diatom in the Southern Ocean, where low iron and manganese availability constrain primary production and biogeochemical activity. The molecular mechanisms used by polar diatoms, including F. cylindrus, to cope with trace metal limitations remain largely unexplored.

pLM‐Repeat: Exploiting the sequence representations of protein language models for sensitive repeat detection

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Duplication is an essential mechanism of molecular evolution, which operates across biological scales, from whole genomes to single basepairs. Its study is central to understanding protein evolution, but the detection of duplication events often becomes challenging over evolutionary time, due to the accumulating sequence divergence.

A dynamic protein interactome drives energy conservation and electron flux in Thermococcus kodakarensis

Applied and Environmental Microbiology
Life is supported by energy gains fueled by catabolism of a wide range of substrates, each reliant on the selective partitioning of electrons through redox (reduction and oxidation) reactions.

Presence of structural homologs of ubiquitin in haloalkaliphilic Archaea [PDF]

, 2010
Ubiquitin, a protein widely conserved in eukaryotes, is involved in many cellular processes, including proteolysis. While sequences encoding ubiquitin-like proteins have not been identified in prokaryotic genomes sequenced so far, they have revealed the ...

Thiol post‐translational modifications modulate allosteric regulation of the OpcA–G6PDH complex through conformational gate control

Protein Science, Volume 35, Issue 5, May 2026.
Abstract In cyanobacteria, the redox‐sensitive protein OpcA acts as a metabolic switch for G6PDH, enabling rapid adjustment of reducing power generation from glycogen catabolism and thereby precisely regulating carbon flux between anabolic and catabolic pathways.

Characterization of the Orphan Cytochrome P450 CYP107J1 From Bacillus subtilis Through Peroxygenase Activity Engineering

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
The orphan cytochrome P450 CYP107J1 with unknown redox partners was rationally modified into H2O2‐driven form. The QE (E251Q/T252E) mutant produced valuable chemicals by simply mixing the enzyme with substrate and H2O2. ABSTRACT Cytochrome P450 monooxygenases (P450s) not only play many physiological roles in oxidative metabolism but are also promising ...

Emerging Technologies for Biobutanol Production via Syngas Fermentation

GCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...
