Clustering as a Means To Control Nitrate Respiration Efficiency and Toxicity in Escherichia coli

mBio, 2019
Respiration is a fundamental process that has to optimally respond to metabolic demand and environmental changes. We previously showed that nitrate respiration, crucial for gut colonization by enterobacteria, is controlled by polar clustering of the ...

Confocal laser scanning microscope, raman microscopy and western blotting to evaluate inflammatory response after myocardial infarction [PDF]

, 2015
Cardiac muscle necrosis is associated with inflammatory cascade that clears the infarct from dead cells and matrix debris, and then replaces the damaged tissue with scar, through three overlapping phases: the inflammatory phase, the proliferative phase

Proteinvermittelte Kupfer‐Redoxregulation: Rolle von Disulfidbrücken und allosterischer Modulation

Angewandte Chemie, 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.

Two-stage binding of mitochondrial ferredoxin-2 to the core iron-sulfur cluster assembly complex

Nature Communications
Iron-sulfur (FeS) protein biogenesis in eukaryotes begins with the de novo assembly of [2Fe-2S] clusters by the mitochondrial core iron-sulfur cluster assembly (ISC) complex.

Probing the Active Site of Class 3 L-Asparaginase by Mutagenesis: Mutations of the Ser-Lys Tandems of ReAV

Biomolecules
The ReAV enzyme from Rhizobium etli, a representative of Class 3 L-asparaginases, is sequentially and structurally different from other known L-asparaginases. This distinctiveness makes ReAV a candidate for novel antileukemic therapies.
