Protein‐Driven Copper Redox Regulation: Uncovering the Role of Disulphide Bonds and Allosteric Modulation

Angewandte Chemie International Edition, EarlyView.
Copper binding triggers structural changes that expose a reactive disulphide bridge, enabling intrinsic Cu(II) reduction in folded proteins. SAXS, XAS, and QM/MM simulations reveal how globular proteins such as HSA and SOD1 employ disulphide‐mediated dynamics to modulate site accessibility and control copper redox chemistry.

Lipid Pocket Binders Impose Allosteric Changes of Protein Dynamics Around the Active Site of the Protein Kinase p38α

Angewandte Chemie International Edition, EarlyView.
Used in search of novel allosteric sites in the serine/threonine kinase p38α, NMR spectroscopy reveals a dynamic coupling between the catalytic and lipid pockets. The findings uncover a motional interdependence that links distant regions of the enzyme, highlighting the lipid pocket as a promising site for allosteric intervention.

Controlling the Field: Memory, Labor, and Ethics in Oral Histories of Brazilian Human Genetics

Berichte zur Wissenschaftsgeschichte, EarlyView.
This article examines how oral histories of twentieth‐century human genetics in Brazil reveal the politics of memory of fieldwork. Through a comparative analysis of interviews with prominent geneticist Francisco M. Salzano and technician Girley V. Simões, who worked with him for most of his career, this study explores the narrative strategies each ...

Engineered Bacterial Ligand From Streptococcus pneumoniae on Macroporous Resins for Selective Affinity Capture of Secretory IgA

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Secretory immunoglobulin A (sIgA) is a promising emerging biopharmaceutical candidate, but it currently lacks a standardized platform for purification. To address this, a novel affinity chromatography resin was developed by immobilizing protein variants of the Streptococcus pneumoniae surface protein, SpsA, as an affinity ligand.
