Electron Flow through Metalloproteins [PDF]

Chemical Reviews, 2010
Electron transfers in photosynthesis and respiration commonly occur between metal-containing cofactors that are separated by large molecular distances. Understanding the underlying physics and chemistry of these biological electron transfer processes is the goal of much of the work in our laboratories.

Extracellular regulation of metalloproteinases [PDF]

, 2015
Matrix metalloproteinases (MMPs) and adamalysin-like metalloproteinase with thrombospondin motifs (ADAMTSs) belong to the metzincin superfamily of metalloproteinases and they play key roles in extracellular matrix catabolism, activation and inactivation ...

Concentration‐Based Analysis of Metal‐Induced Tau Fibrillar versus non‐fibrillar Aggregation: Implications for Neurotoxicity in Alzheimer's Disease

ChemistryOpen, EarlyView.
Tau protein aggregation and fibrillation have been examined in relationship to three metal ions in this study. The research was conducted to see the effects of Zn2+, Cu2+ and Fe3+ ions at different concentrations on tau′s conformation, cytotoxicity in SH‐SY5Y cells, and free thiol levels.

Marked changes in electron transport through the blue copper protein azurin in the solid state upon deuteration

, 2012
Measuring electron transport (ETp) across proteins in the solid-state offers a way to study electron transfer (ET) mechanism(s) that minimizes solvation effects on the process.

Insights Into the Conformational Dynamics of the Cytoplasmic Domain of Metal‐Sensing Sensor Histidine Kinase ZraS

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT ZraS is a metal sensor integral to ZraPSR, a two‐component signaling system found in enterobacters. It belongs to a family of bifunctional sensor histidine kinases (SHKs) and is speculated to sense zinc‐induced stress on the bacterial envelope.
