Proteins, proteins everywhere [PDF]
The first protein structures were determined by x-ray crystallography in 1957 by John C. Kendrew and Max F. Perutz. As a bioinorganic chemist, I was delighted that the structures were myoglobin and hemoglobin, both heme proteins with big, beautiful iron atoms.

Proteins are polymers of amino acids linked via α-peptide bonds. They can be represented as primary, secondary, tertiary, and even quaternary structures, but from a nutritional viewpoint only the primary (amino acid) sequence is of interest. Similarly, although there are many compounds in the body that can be chemically defined as amino acids, we are ...

Laminopathies: what can humans learn from fruit flies
Lamin proteins are type V intermediate filament proteins (IFs) located inside the cell nucleus. They are evolutionarily conserved and have similar domain organization and properties to cytoplasmic IFs. Lamins provide a skeletal network for chromatin, the

Precise Similarity of Many Human Proteins to Proteins of Prokarya [PDF]
Proteins originated in early forms of life and have long survived, because they have always been required. Some recognizably similar proteins are found in all sequence comparisons between species, no matter how distant, including prokaryotes and ...

Reorganization of Cell Compartmentalization Induced by Stress
The discovery of intrinsically disordered proteins (IDPs) that do not have an ordered structure and nevertheless perform essential functions has opened a new era in the understanding of cellular compartmentalization.

Bacteriophage Protein–Protein Interactions [PDF]
Bacteriophages T7, λ, P22, and P2/P4 (from Escherichia coli), as well as ϕ29 (from Bacillus subtilis), are among the best-studied bacterial viruses. This chapter summarizes published protein interaction data of intraviral protein interactions, as well as known phage-host protein interactions of these phages retrieved from the literature. We also review

Urine Parameters in Patients with COVID-19 Infection
A urine test permits the measure of several urinary markers. This is a non-invasive method for early monitoring of potential kidney damage. In COVID-19 patients, alterations of urinary markers were observed.
