High-resolution electrochemical STM of redox metalloproteins [PDF]
Electrochemical studies of redox active metalloproteins have become an increasingly fruitful area of study in recent years, particularly with the single-molecule resolution capability of electrochemical scanning tunnelling microscopy (EC-STM) which ...

Abstract The mood stabilizers lithium and valproate are psychotropic medications widely used in clinical practice. Despite their proven benefits, many individuals stop their treatment due to the adverse effects. Chronic diarrhoea is a common reason for discontinuation of these drugs; however, the underlying mechanisms are unknown.

Magnetic Relaxometry of Methemoglobin by Widefield Nitrogen-Vacancy Microscopy [PDF]
Hemoglobin (Hb) is a multifaceted protein, classified as a metalloprotein, chromoprotein, and globulin. It incorporates iron, which plays a crucial role in transporting oxygen within red blood cells. Hb functions by carrying oxygen from the respiratory organs to diverse tissues in the body, where it releases oxygen to fuel aerobic respiration, thus ...

Metallochaperones regulate intracellular copper levels. [PDF]
Copper (Cu) is an important enzyme co-factor that is also extremely toxic at high intracellular concentrations, making active efflux mechanisms essential for preventing Cu accumulation. Here, we have investigated the mechanistic role of metallochaperones

Redirecting Intermediary Metabolism to Counteract Cyanide Poisoning
Cyanide is coined “the classic metabolic poison”; however, FDA‐approved cyanide chelators do not counteract cyanide's metabolic damage. Here, we review the mechanisms of cyanide toxicity, with a focus on intermediary metabolism. We present the theory that, within the innate plasticity of the metabolome, there may reside metabolic pathways that can ...

AutoDock4Zn: An Improved AutoDock Force Field for Small-Molecule Docking to Zinc Metalloproteins
Zinc is present in a wide variety of proteins and is important in the metabolism of most organisms. Zinc metalloenzymes are therapeutically relevant targets in diseases such as cancer, heart disease, bacterial infection, and Alzheimer’s disease.

Stick number of non-paneled knotless spatial graphs [PDF]
We show that the minimum number of sticks required to construct a non-paneled knotless embedding of $K_4$ is 9 and of $K_5$ is 12 or 13. We use our results about $K_4$ to show that the probability that a random linear embedding of $K_{3,3}$ in a cube is in the form of a M\"{o}bius ladder is $0.97380\pm 0.00003$, and offer this as a possible explanation

In the context of the AMBER parameterization, a new force field is developed and validated for the simulation of cadmium(II)‐binding proteins. The proposed force field takes into account the polarization effect produced by the central ion on its surroundings.

Bioavailability of Metal Ions and Evolutionary Adaptation
The evolution of life on earth has been a long process that began nearly 3,5 x 109 years ago. In their initial moments, evolution was mainly influenced by anaerobic environments; with the rise of O2 and the corresponding change in bioavailability of ...

The Energetics of Electron Transfer in Redox‐DNA Layers Mimics That of Redox Proteins
The electron transfer in ferrocene‐labeled DNA (Fc‐DNA) layers mimics that of redox proteins, featuring a low reorganization energy (λ). The origin of the low λ in Fc‐DNA was unveiled by high‐scan‐rate cyclic voltammetry and molecular dynamics simulations, implying Fc‐DNA as a versatile tool to open new avenues in understanding the ET in biological ...
