Proteins, proteins everywhere [PDF]

open access: yesScience, 2021
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.

Protein [PDF]

open access: yesAdvances in Nutrition, 2011
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

open access: yesCellular & Molecular Biology Letters, 2018
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]

open access: yes, 2007
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 ...

Recombinant nanobody against MUC1 tandem repeats inhibits growth, invasion, metastasis, and vascularization of spontaneous mouse mammary tumors

open access: yesMolecular Oncology, 2022
Alteration in glycosylation pattern of MUC1 mucin tandem repeats during carcinomas has been shown to negatively affect adhesive properties of malignant cells and enhance tumor invasiveness and metastasis.

Reorganization of Cell Compartmentalization Induced by Stress

open access: yesBiomolecules, 2022
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.

Kinetic Studies on the Transport of Cytoplasmically Synthesized Proteins into the Mitochondria in Intact Cells of Neurospora crassa [PDF]

open access: yes, 1977
The transport of cytoplasmically synthesized mitochondrial proteins was investigated in whole cells of Neurospora crassa, using dual labelling and immunological techniques.

Bacteriophage Protein–Protein Interactions [PDF]

open access: yes, 2012
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

Idiosyncratic evolution of conserved eukaryote proteins that are similar in sequence to archaeal or bacterial proteins [PDF]

open access: yes, 2008
Sequence comparisons have been made between the proteins of 571 prokaryote species including 46 archaea and 525 bacteria and the set of human proteins.

Urine Parameters in Patients with COVID-19 Infection

open access: yesLife, 2023
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.
