Toxic Metal Species and ‘Endogenous’ Metalloproteins at the Blood–Organ Interface: Analytical and Bioinorganic Aspects

Molecules, 2021
Globally, human exposure to environmental pollutants causes an estimated 9 million deaths per year and it could also be implicated in the etiology of diseases that do not appear to have a genetic origin.

Bioinformatics of Metalloproteins and Metalloproteomes

Molecules, 2020
Trace metals are inorganic elements that are required for all organisms in very low quantities. They serve as cofactors and activators of metalloproteins involved in a variety of key cellular processes.

Conformational selection underlies recognition of a molybdoenzyme by its dedicated chaperone. [PDF]

PLoS ONE, 2012
Molecular recognition is central to all biological processes. Understanding the key role played by dedicated chaperones in metalloprotein folding and assembly requires the knowledge of their conformational ensembles.

Functional Expression and Characterization of a Panel of Cobalt and Iron-Dependent Nitrile Hydratases

Molecules, 2020
Nitrile hydratases (NHase) catalyze the hydration of nitriles to the corresponding amides. We report on the heterologous expression of various nitrile hydratases.

Inter-Subunit Dynamics Controls Tunnel Formation During the Oxygenation Process in Hemocyanin Hexamers

Frontiers in Molecular Biosciences, 2021
Hemocyanin from horseshoe crab in its active form is a homo-hexameric protein. It exists in open and closed conformations when transitioning between deoxygenated and oxygenated states.

Dependence of TIMP-1 plasma levels on preanalytical specimen handling [PDF]

, 2008
Background: Tissue inhibitor of metalloproteinases-1 (TIMP-1) in blood might be a helpful biomarker in various diseases. However, various authors report that TIMP-1 is dependent on preanalytical procedures.

Pico-meter resolution structure of the coordination sphere in the metal-binding site in a metalloprotein by NMR.

Journal of the American Chemical Society, 2020
Most of our understanding of chemistry derives from atomic-level structures obtained with single crystal X-ray diffraction. Metal centers in X-ray structures of small organometallic or coordination complexes are often extremely well defined, with errors ...

Redox-controlled reorganization and flavin strain within the ribonucleotide reductase R2b–NrdI complex monitored by serial femtosecond crystallography

eLife, 2022
Redox reactions are central to biochemistry and are both controlled by and induce protein structural changes. Here, we describe structural rearrangements and crosstalk within the Bacillus cereus ribonucleotide reductase R2b–NrdI complex, a di-metal ...

From Zn to Mn: the study of novel manganese-binding groups in the search for new drugs against tuberculosis. [PDF]

, 2011
In most eubacteria, apicomplexans, and most plants, including the causal agents for diseases such as malaria, leprosy, and tuberculosis, the methylerythritol phosphate pathway is the route for the biosynthesis of the C(5) precursors to the essential ...

Stealthy microbes: How Neisseria gonorrhoeae hijacks bulwarked iron during infection

Frontiers in Cellular and Infection Microbiology, 2022
Transition metals are essential for metalloprotein function among all domains of life. Humans utilize nutritional immunity to limit bacterial infections, employing metalloproteins such as hemoglobin, transferrin, and lactoferrin across a variety of ...
