This study investigates the role of the GT1 domain in Arabidopsis RNase J by showing it binds dsRNA and DNA, affects enzyme solubility, and is critical for dsRNA removal in plastids.

This study shows that cyanophage NblA proteins negatively affect oceanic cyanobacterial photosynthesis by accelerating infection, degrading the phycobilisome, and reducing light harvesting efficiency.

The paper identifies USP15 as a fourth proteasome-associated DUB, showing it binds transiently to proteasomes and selectively disassembles short polyubiquitin chains.

The paper shows that COX-2 proteolysis generates catalytically inactive fragments that affect mitochondrial function and cell proliferation in colon tumors.

This study identifies NPQ-independent mechanisms in Chlorella ohadii that protect against oxidative stress under high light.

This study maps phosphorylation sites in photosystem I and its antenna proteins of Chlorella sp. under different light conditions and identifies oxidative damage in the psaD subunit.

The paper identifies proteolytic events in neurons during excitotoxicity using N-terminomics, revealing calpain-mediated cleavage of synaptic proteins and potential therapeutic targets for neuroprotection.

This study identifies that Helicobacter pylori VacA is processed in endosomes by proteases into active forms that mediate intracellular effects, revealing a novel mechanism of toxin activation.
