The paper presents the crystal structure of Nmar_0206 from Nitrosopumilus maritimus, revealing a conserved interdomain linker loop that influences homodimer stability and contributes to the enzyme's energy efficiency in the 3HP/4HB cycle.

This study presents the most comprehensive pangenomic analysis of SAR11 subclade IIIa, revealing ecological and metabolic differentiation across its subgroups and bridging marine and freshwater adaptations.

This study presents the first high-resolution crystal structure of a bifunctional enzyme involved in the 3HP/4HB cycle in Nitrosopumilus maritimus, revealing its dual catalytic activities.

The paper investigates how 4HBD, a key enzyme in archaeal carbon fixation, adapted structurally to become oxygen-tolerant, revealing evolutionary changes that enabled aerobic metabolism.

This study identifies a marine Thaumarchaeota clade that uses aerobic heterotrophy and RuBisCO-mediated carbon metabolism, revealing an evolutionary link between anaerobic and aerobic lineages.

This study tests diversity-productivity, diversity-invasibility, and diversity-stability hypotheses in cover crop mixtures, finding that diversity does not consistently increase biomass, weed suppression, or stability.
