Pseudo-Contact NMR Shifts over the Paramagnetic Metalloprotein CoMMP-12 from First Principles.

Angewandte Chemie, 2016
Long-range pseudo-contact NMR shifts (PCSs) provide important restraints for the structure refinement of proteins when a paramagnetic metal center is present, either naturally or introduced artificially.

Synthesis, characterization and antimicrobiological activity of copper(II) complexes containing ligands derived from azoles and coumarins

European Journal of Inorganic Chemistry, Accepted Article.
Four Cu(II) complexes with coumarin‐derived ligands were synthesized and fully characterized, confirming a ratio of 1:1 ligand to metal. The complex C3 presented a geometry between square pyramid and trigonal bipyramid with a supramolecular arrangement ruled by hydrogen bonding.

Breaking Boundaries: Chronic Diseases and the Frontiers of Immune Microenvironments

Med Research, EarlyView.
ABSTRACT The immune microenvironment includes immune cells, cytokines, extracellular matrix, vesicles, etc. The interactions between these components form a unique local immune microecology. Although immunity serves as the defense against external pathogens, aberrant immune activation often contributes to disease development.

De Novo Design of an Allosteric Metalloprotein Assembly with Strained Disulfide Bonds.

Journal of the American Chemical Society, 2016
A major goal in metalloprotein design is to build protein scaffolds from scratch that allow precise control over metal coordination. A particular challenge in this regard is the construction of allosteric systems in which metal coordination equilibria ...

Extracting Trends From NMR Data With TrAGICo: A Python Toolbox

Magnetic Resonance in Chemistry, EarlyView.
TrAGICo is a Python collection of functions for the extraction and analysis of serial NMR spectroscopy data. In this tutorial, we show several practical examples, highlighting its utility for various chemical NMR applications, such as extraction of the chemical shift temperature dependence in paramagnetic systems, relaxation studies, and reaction ...

Solid-State Metalloproteins—An Alternative to Immobilisation

Molecules, 2016
This commentary outlines a protein engineering approach as an alternative to immobilisation developed in our laboratory. We use a recombinant silk protein into which metal active sites can be incorporated to produce solid-state metalloprotein materials ...

Beyond the passive interactions at the nano-bio interface: evidence of Cu metalloprotein-driven oxidative dissolution of silver nanoparticles

Journal of Nanobiotechnology, 2016
BackgroundIn a biological system, an engineered nanomaterial (ENM) surface is altered by adsorbed proteins that modify ENM fate and toxicity. Thus far, protein corona characterizations have focused on protein adsorption, interaction strength, and ...

Revisiting Fused‐Pyrrolo‐1,10‐Phenanthroline Derivatives: Novel Transformations and Stability Studies

ChemistryOpen, EarlyView.
The synthesis of new pyrrolo[3',4':3,4]pyrrolo[1,2‐a][1,10]phenanthroline derivatives is performed starting from [3+2] cycloaddition of in situ generated ylides, followed by cycloadducts oxidation and other transformations. The structures of the unexpected intermediates and final compounds are obtained from nuclear magnetic resonance and single‐crystal

Electrochemistry of metalloproteins

, 1985
The direct (unmediated) electrochemistry of a variety of redox proteins has been studied at a range of electrode materials. Electrochemical studies using cytochromes, iron-sulphur proteins and copper proteins show a marked enhancement of the heterogeneous electron-transfer rate at the "edge" plane of pyrolytic graphite. Parallel ESCA studies have shown
