Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Regulation of Mitochondrial Electron Transport Chain Assembly
Mitochondrial function depends on the correct synthesis, transport, and assembly of proteins and cofactors of the electron transport chain. The initial idea that the respiratory chain protein complexes (RCCs) were independent structures in the inner ...

Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Characterization of the Novel Photosynthetic Protein PPP7 involved in Cyclic Electron Flow around PSI [PDF]
Photosynthetic organisms are able to convert light energy into chemical energy by the operation of the two photosystems, the cytochrome b6/f complex and the ATPase.

Interpreting the effects of DNA polymerase variants at the structural level
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

The electron transport chains of Neisseria meningitidis [PDF]
Neisseria meningitidis contains c-type and b-type cytochromes. Oxidation of c-type and b-type cytochromes by oxygen was observed in both cells grown under aerobic and denitrifying conditions, whereas oxidation of cytochromes by nitrite was only seen in ...

Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
