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

open access: yesFEBS 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.

Structural biology of ferritin nanocages

open access: yesFEBS 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 ...

What do we mean by building function? [PDF]

open access: yes, 1984
Scientific approaches to architecture usually avoid the issue of building form, preferring to focus on function. But how can there be a theory of function without a systematic analysis of the key architectural variable of form?

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Battle for Inbox and Bucks

open access: yesJournal of Quantitative Description: Digital Media
Despite its proven pervasiveness and effectiveness, the role of email in political campaigns has been understudied. In this article, we seek to understand the use of emails by Donald Trump's and Joe Biden's campaigns during the 2020 U.S.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

ZFP36 Protects against Abdominal Aortic Aneurysm Formation by Regulating Vascular Smooth Muscle Phenotypic Switch

open access: yesResearch
Abdominal aortic aneurysm (AAA) is a life-threatening aortic disease without effective pharmacological therapies. Mounting evidences suggested that RNA-binding proteins (RBPs) exert pivotal roles in various diseases including AAA.

Rawls’ Political Constructivism as a Judicial Heuristic: A Response to Professor Allen [PDF]

open access: yes, 1999
In her Dunwody Lecture, Professor Anita Allen insightfully calls our attention to the social contract tropes that pepper American case law. She claims that these tropes function ideologically, disguising politics, biases, and raw power in judicial ...

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
