Ecology and Evolution, Volume 16, Issue 5, May 2026.Here, we de novo assembled the chloroplast genomes of Ranunculus arvensis and Ranunculus laetus, providing comprehensive comparative analysis with 21 congeners. The genomes exhibited conserved quadripartite structures with no major rearrangements, though lineage‐specific variations in atpH position were detected in two species.

Ecology and Evolution, Volume 16, Issue 5, May 2026.In this study, nine complete chloroplast genomes of Cousinia species endemic to the Pamir–Alay mountain system were sequenced and analyzed together with previously published plastomes and nuclear ribosomal ITS data. ABSTRACT Cousinia (Asteraceae: Cardueae) represents one of the most species‐rich genera within the Irano–Turanian floristic region, yet ...

Ecology and Evolution, Volume 16, Issue 5, May 2026.This study presents the first complete chloroplast genomes of two medicinally important Stachys species, S. persica and S. germanica. Comparative phylogenomic analyses revealed highly conserved genomes with lineage‐specific variations, identified hypervariable regions as candidate DNA barcodes, and detected signatures of positive selection in the petB ...

Highly Dynamic Interactions Maintain Kinetic Stability of the ClpXP Protease During the ATP-Fueled Mechanical Cycle [PDF]
, 2016 The ClpXP protease assembles in a reaction in which an ATP-bound ring hexamer of ClpX binds to one or both heptameric rings of the ClpP peptidase. Contacts between ClpX IGF-loops and clefts on a ClpP ring stabilize the complex.

Chemical Activators of ClpP: Turning Jekyll into Hyde
Chemistry & Biology, 2011 Casein lytic peptidase P (ClpP) is a serine peptidase that, when coupled to its cognate ATPase, facilitates the controlled degradation of both damaged and unwanted proteins in bacteria. In this issue of Chemistry & Biology, Leung et al. (2011) report a small molecule screen against ClpP, from which they identified four structurally distinct compounds ...

Cell Division Protein FtsZ Is Unfolded for N-Terminal Degradation by Antibiotic-Activated ClpP
mBio, 2020 Antibiotic acyldepsipeptides (ADEPs) deregulate ClpP, the proteolytic core of the bacterial Clp protease, thereby inhibiting its native functions and concomitantly activating it for uncontrolled proteolysis of nonnative substrates.

Identifying Subcellular Structure Components in Escherichia Coli by Crosslinking and SEC‐MS
PROTEOMICS, Volume 26, Issue 5, Page 27-36, May 2026.ABSTRACT Cells are comprised of a broad spectrum of structures that compartmentalize biochemical and signaling mechanisms. These structures can be comprised of many biomolecules, but especially lipids, proteins, and nucleic acids. Techniques are limited to quantify or discover new subcellular structures.

EMBO reports, 2018 Mitochondria are fundamental for cellular metabolism as they are both a source and a target of nutrient intermediates originating from converging metabolic pathways, and their role in the regulation of systemic metabolism is increasingly recognized. Thus, maintenance of mitochondrial homeostasis is indispensable for a functional energy metabolism of ...
