Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Relationship between strain localization and catastrophic rupture
, 2007 In order to explore a prior warning to catastrophic rupture of heterogeneous media, like rocks, the present study investigates the relationship between surface strain localization and catastrophic rupture.

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.

An experimental investigation of the behaviour of steels over large temperature and strain rate ranges [PDF]
, 2013 During forging and machining manufacturing processes, the material is subject to large strains at high strain rates which provoke local heating and microstructural changes.

Geochemistry, Geophysics, GeosystemsIn convergent high‐pressure settings dominated by dry mafic rocks, strain has been proposed to be predominantly localized in eclogite. However, the processes initiating strain localization, accommodating strain and rheological consequences remain to be ...

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Aging‐Induced Ductile‐Brittle‐Ductile Transition in High‐Entropy Alloys and its Implications
Advanced ScienceTemper embrittlement, characterized by a dramatic loss of ductility within a narrow temperature window, is ubiquitous in conventional alloys but is not reported in compositionally complex or high‐entropy alloy systems. Here, an unexpected ductile–brittle–
