Strategies and mechanisms of precision genome engineering: From gene editing to genome writing
iMetaOmics, EarlyView.In this review, we examined the progression of genome manipulation from stochastic nuclease‐mediated cutting toward precise editing and programmable genome writing. We discussed tools like multi‐kilobase RNA‐guided integrators and Artificial Intelligence (AI)‐designed effectors and showed how these advances enable researchers to treat genomes as ...

DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity
Small, Volume 22, Issue 43, 3 August 2026.DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Photosynthetic primary production in the Mesoproterozoic
New Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

ChemBioChem, Volume 27, Issue 11, 15 June 2026.This study reveals how Clostridium pasteurianum BC1's clade E carbon monoxide dehydrogenase (CODH‐III) achieves catalytic activity even without its native maturation proteins (CooCTJ), stimulating new interpretations of CODH maturation. Electron paramagnetic resonance (EPR) spectroscopy displays canonical C‐cluster signal.

mLife, Volume 5, Issue 3, Page 312-324, June 2026.Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

On the rôle of the carotenoids in photosynthesis in Rhodospirillum rubrum [PDF]
Biochimica et Biophysica Acta, 1950 The photosynthetic action spectrum of Rhodospirillum rubrum Esmarck strain 4 was determined. Some carotinoids were found capable of absorbing photosynthetically active light. Apparently, however, the main carotenoid, spirilloxanthin, does not participate in photosynthesis.

Construction of a CO2‐Fixing Compartment Using a Shape‐Transforming DNA Scaffold
Chemistry – A European Journal, Volume 32, Issue 19, 22 May 2026.A shape‐transforming DNA scaffold encapsulates RuBisCO within a controllable, self‐contacting compartment that mimics the carboxysome. The scaffold switches between open and closed states, enabling direct comparison of identical enzyme populations in different microenvironments.

Unique double concentric ring organization of light harvesting complexes in Gemmatimonas phototrophica. [PDF]
PLoS Biology, 2017 The majority of life on Earth depends directly or indirectly on the sun as a source of energy. The initial step of photosynthesis is facilitated by light-harvesting complexes, which capture and transfer light energy into the reaction centers (RCs). Here,
