Human IDO2 exhibits unique binding affinities distinct to those of human IDO1

The FEBS Journal, EarlyView.
Although indoleamine 2,3‐dioxygenase 2 (IDO2) is highly homologous to IDO1, it displays markedly lower catalytic activity. We found that IDO2 binds L‐tryptophan (L‐Trp) in a flipped orientation stabilized by the IDO2‐specific residue His143. Replacement of His143 with the IDO1‐equivalent tyrosine restored an IDO1‐like binding mode and increased ...

GCN2 in proteostasis: structural logic, signalling networks and disease

The FEBS Journal, EarlyView.
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.

ALOX15 mediates thrombin‐induced myristoylation, trafficking, and interaction of protease‐activated receptors, leading to platelet activation and hemostasis

The FEBS Journal, EarlyView.
The role of PARs in platelet function is fairly known; however, the underlying mechanisms are not fully understood. We report that thrombin myristoylates PAR4 in mouse platelets and PAR1 and PAR4 in human platelets, facilitating their membrane transport and interaction, leading to PAR3/4 heterodimers in mice and PAR1/4 heterodimers in humans.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

The FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Proteolytic remodelling of the extracellular matrix by pericytes

The FEBS Journal, EarlyView.
Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.
