Ab initio analysis of the x-ray absorption spectrum of the myoglobin-carbon monoxide complex: Structure and vibrations

, 2010
We present a comparison between Fe K-edge x-ray absorption spectra of carbonmonoxy-myoglobin and its simulation based on density-functional theory determination of the structure and vibrations and spectral simulation with multiple-scattering theory.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Reflections on the Origin of Coded Protein Biosynthesis

Biomolecules
The principle of continuity posits that some central features of primordial biocatalytic mechanisms should still be present in the genetically dependent pathway of protein synthesis, a crucial step in the emergence of life.

Engineering tyrosine-based electron flow pathways in proteins: The case of aplysia myoglobin [PDF]

, 2012
Tyrosine residues can act as redox cofactors that provide an electron transfer ("hole-hopping") route that enhances the rate of ferryl heme iron reduction by externally added reductants, for example, ascorbate.

Trace Element Analysis in Human Neuroblastoma Cell Spheroids Supplemented With ZnCl2 by Micro‐XRF

X-Ray Spectrometry, EarlyView.
ABSTRACT Neuroblastoma, the most common extracranial solid tumor of childhood, is responsible for ~10% of pediatric cancer deaths and has high potential for metastasis. Metals are extremely important in biological processes, and changes in their levels have been correlated with the development of cancerous growth.

Molecular dynamics simulations of metalloproteins: A folding study of rubredoxin from Pyrococcus furiosus

AIMS Biophysics, 2018
The constant increase of computational power has made feasible to investigate the folding mechanism of small proteins using molecular dynamics (MD). Metal-binding proteins (metalloproteins) are usually complicated to model, largely due to the presence of
