Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Ferredoxin-dependent methane formation from acetate in cell extracts of Methanosarcina barkeri (strain MS) [PDF]

, 1990
Cell extracts of Methanosarcina barkeri grown on acetate catalyzed the conversion of acetyl-CoA to CO2 and CH4 at a specific rate of 50 nmol·min−1·mg−1.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Daily Heat Stress Induces Donor‐Side Limitation of PSI Via Downregulation of the Cyt b6f Complex

Plant, Cell &Environment, EarlyView.
ABSTRACT The rapidly warming climate is driving increasingly frequent and intense heat waves worldwide, posing major challenges to plant metabolism and growth. Despite the central role of photosynthesis in plant growth, the effects of prolonged heat stress on the primary reactions of photosynthesis remain poorly understood.

Design Principles of Plant Thermotolerance: Integrating Photosynthesis, Reproduction, and Field Resilience in a Warming Climate

Plant, Cell &Environment, EarlyView.
ABSTRACT Global food security is increasingly threatened by climate change, as rising temperatures compromise the yields of major staple crops, including wheat, rice, and maize. Enhancing plant thermotolerance has therefore become a critical priority for sustaining agricultural productivity.

The crystal structure of FusC in complex with ferredoxin reveals two distinct ferredoxin bindings sites.

, 2018
(A) Crystals of the FusC:ferredoxin complex (left) and SDS-PAGE of resolubilized crystals (right) showing that intact ferredoxin (approximately 10 kDa) is present in the crystals and peptides identified by mass spectrometry from regions of a gel excised ...

Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...

The Ferredoxin-Like Proteins HydN and YsaA Enhance Redox Dye-Linked Activity of the Formate Dehydrogenase H Component of the Formate Hydrogenlyase Complex

Frontiers in Microbiology, 2018
Formate dehydrogenase H (FDH-H) and [NiFe]-hydrogenase 3 (Hyd-3) form the catalytic components of the hydrogen-producing formate hydrogenlyase (FHL) complex, which disproportionates formate to H2 and CO2 during mixed acid fermentation in enterobacteria ...

Universal and Lineage‐Specific Patterns in the Distribution of ECOD Domain Homology Groups Across Superkingdoms

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1644-1657, October 2026.
ABSTRACT Proteins are built from modular domains that serve as fundamental units of structure and evolution. While individual domains have been extensively cataloged, their collective distribution across the lineages of life has remained poorly resolved.
