Nature's Nanotech Warriors: The Role of Metalloproteins and Protein Cages for Environmental Remediation

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Cartoon representation of five major classes of metalloproteins and their brief mechanisms of bioremediation. The five classes include metallothioneins, metal‐precipitating enzymes, P.‐type ATPases, protein cages, and synthetic metalloproteins (de novo‐designed proteins/peptides for selective adsorption). These natural and engineered protein structures

Reversible Regime Change: Climate‐Driven Phytoplankton Community Shifts in the Cariaco Basin, Venezuela

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Phytoplankton communities are integral to oceanic biogeochemical cycles and are sensitive indicators of climate‐driven environmental variability. Long‐term time series capture this variability, allowing us to unravel the effects of environmental change on local communities.

Dominance and toxicity without lethality: Exploring biomass, cyanometabolites, and Daphnia responses across Cyanobacterial strains

Journal of Phycology, Volume 62, Issue 3, Page 801-817, June 2026.
Abstract Cyanobacteria are cosmopolitan, important components of biomass with a remarkable ability to synthesize a diverse array of bioactive compounds, some of which may have toxic effects on other organisms and ecosystems. In this study, filamentous cyanobacterial strains isolated predominantly from temperate European freshwaters (Aphanizomenon ...

Photoreactions and Structural Changes of Anabaena Sensory Rhodopsin [PDF]

Sensors, 2009
Anabaena sensory rhodopsin (ASR) is an archaeal-type rhodopsin found in eubacteria. The gene encoding ASR forms a single operon with ASRT (ASR transducer) which is a 14 kDa soluble protein, suggesting that ASR functions as a photochromic sensor by activating the soluble transducer. This article reviews the detailed photoreaction processes of ASR, which

Functional and structural insights into cyanobacterial CO2 concentrating mechanisms: from compartmentalization to regulation

The Plant Journal, Volume 126, Issue 5, June 2026.
Significance Statement Life on Earth depends on photosynthetic CO2 fixation via the Calvin–Benson–Bassham cycle to form organic carbon. This process evolved first in cyanobacteria and was later conveyed to eukaryotes, giving rise to plastids in algae and plants. To cope with low atmospheric CO2 concentrations that developed over the course of evolution,

Long‐Term Safety and Efficacy of Pegvaliase in Japanese Adults With Phenylketonuria: Final Results of a Phase III Trial

JIMD Reports, Volume 67, Issue 3, May 2026.
ABSTRACT Phenylketonuria (PKU) is an inborn error of metabolism leading to phenylalanine (Phe) accumulation and consequent neurological, neurocognitive, and psychiatric symptoms. Pegvaliase, a pegylated recombinant phenylalanine ammonia lyase that metabolizes Phe, effectively reduced blood Phe in phase III studies in the United States. This multicenter,

Surface slicks structure microbial and viral neuston in relation to biogeochemical conditions

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract The sea‐surface microlayer (hereafter microlayer), which forms the interface between the ocean and atmosphere, plays a key role in nutrient cycling and microbial dynamics. Coastal slicks, which are viscous and biogenic surface films, often serve as hotspots for microbial activity, yet their structure and interactions remain incompletely ...

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.
