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

open access: yesThe 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,

Electron and Proton Flux for Carbon Dioxide Reduction in Methanosarcina barkeri During Direct Interspecies Electron Transfer

open access: yesFrontiers in Microbiology, 2018
Direct interspecies electron transfer (DIET) is important in diverse methanogenic environments, but how methanogens participate in DIET is poorly understood.

Facile Synthesis of H‐L‐Photo‐Lysine and Its Genetic Incorporation Into Proteins

open access: yesChemBioChem, Volume 27, Issue 10, 27 May 2026.
An efficient synthesis of a diazirine‐based noncanonical amino acid (ncAA), photo‐lysine (photoK), is reported, and its genetic incorporation into green fluorescent protein (GFP) is demonstrated. PhotoK‐enabled crosslinking is used to capture substrates and interaction partners of SIRT6 in vitro, in Escherichia coli, and in HEK293 cell lysates ...

Acetogenic Methane‐Carbon Monoxide Comproportionation: An Exergonic but Unobserved Microbial Metabolism

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Microbial metabolism relies on redox reactions that exploit chemical disequilibria. While aerobic carbon oxidation, carbon fixation, and fermentation are well studied, the broader space of anaerobic carbon redox reactions remains underexplored.

Immunochemistry and localization of the enzyme disaggregatase in Methanosarcina mazei [PDF]

open access: yesJournal of Bacteriology, 1993
The enzyme disaggregatase (Dag) from Methanosarcina mazei was studied immunochemically. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis of purified Dag under reducing and nonreducing conditions revealed a single band with a 94-kDa molecular mass.

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

open access: yesChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...

The Methanosarcina barkeri genome: comparative analysis with Methanosarcina acetivorans and Methanosarcina mazei reveals extensive rearrangement within methanosarcinal genomes.

open access: yesJournal of bacteriology, 2006
We report here a comparative analysis of the genome sequence of Methanosarcina barkeri with those of Methanosarcina acetivorans and Methanosarcina mazei. The genome of M. barkeri is distinguished by having an organization that is well conserved with respect to the other Methanosarcina spp.

Biotic–Abiotic Hybrid Strategies for Photosynthetic Nitrogen Fixation and Green Ammonia Synthesis

open access: yesChemistryEurope, Volume 4, Issue 4, April 2026.
Biotic‐abiotic photosynthetic systems integrate light‐harvesting semiconductors with nitrogenase's selective N2 reduction under ambient conditions, offering a sustainable alternative to conventional ammonia synthesis. Advancing rational interface design, efficient energy‐reaction coupling, and system integration is critical to realizing scalable, solar‐
