A Conceptual Framework and Methods for Studying the Connectivity of Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

The FEBS Journal, Volume 293, Issue 6, Page 1681-1707, March 2026.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

Structural analysis of the NifL‐NifA complex reveals the molecular basis of anti‐activation of nitrogen fixation gene expression in Azotobacter vinelandii

The FEBS Journal, Volume 293, Issue 6, Page 1643-1663, March 2026.
Understanding the molecular basis of nitrogen fixation is essential for engineering bacteria that fulfill the nitrogen demand of crop plants, reducing our reliance on synthetic nitrogen fertilizers. The bacterial two‐component system comprising the anti‐activator protein (NifL) and the Nif‐specific transcriptional activator (NifA) controls the nitrogen

Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

The FEBS Journal, Volume 293, Issue 6, Page 1708-1726, March 2026.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Evolution of lysine and arginine biosynthesis revealed by substrate specificity of lysine biosynthetic enzymes in Thermus thermophilus

The FEBS Journal, Volume 293, Issue 6, Page 1727-1740, March 2026.
Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.
