The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Determination of the source location of the 2023 Jishishan M6.2 earthquake in Gansu Province

地震科学进展
Based on the P-phase arrival time, we determined the source location of the Jishishan M6.2 earthquake with simulated annealing (SA) method, and quantitatively evaluated the reliability of the results using sample set statistical analysis method.

DIATOM COMPLEXES OF THE IMANDRA LAKE SEDIMENTS IN THE AREA AFFECTED BY HEATED WATER FROM THE KOLA NUCLEAR POWER PLANT

Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
Diatom assemblages in Lake Imandra sediments (Kola Peninsula) were investigated in the area affected by heated discharges from the Kola NPP. Diatoms responses to the environmental changes were analyzed; the main stages in the lake ecosystem development ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
