Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.
A computational model of a human lung cell has been used to understand how SARS-CoV-2 draws on human host cell metabolism to reproduce by researchers at the University of Warwick.
Researchers have recently discovered how the function of therapeutically relevant ion channels is regulated by drug-like small molecules.
A genetic modification in the 'coat' of a brain infection-causing virus may allow it to escape antibodies, according to Penn State College of Medicine researchers.
A high concentration of salt or sugar in the environment will dehydrate microorganisms and stop them from growing.
Thirty years ago, the cloning of the green fluorescent protein GFP, together with genetic engineering tools, revolutionized the field by enabling researchers to fuse a fluorescent 'beacon' to any protein of interest so that it can be directly observed in living cells using fluorescence microscopy.
In many neurodegenerative diseases like Parkinson's, protein aggregates form in the brain and are assumed to contribute to neuronal cell death.
A recent paper examines a mutation of the spike protein of SARS-CoV-2 that has been observed to have arisen independently twice.
A ground-breaking discovery by Centenary Institute scientists has provided new understanding as to the nature of proteins and how they exist and operate in the human body.
The proteins of SARS-CoV-2 play a key role in self-arrangement and particle formation, and current work suggests that an assembly is formed in the lipid bilayer of the endoplasmic reticulum.
Pancreatic cancer cells avert starvation by signaling to nerves, which grow into dense tumors and secrete nutrients. This is the finding of a study with experiments in cancer cells, mice, and human tissue samples published online on November 2 in Cell.
Scientists from the iMolecule group at Skoltech Center for Computational and Data-Intensive Science and Engineering (CDISE) developed BiteNet, a machine learning (ML) algorithm that helps find drug binding sites, i.e. potential drug targets, in proteins.
The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells to contribute its machinery to assist in its propagation.
Scientists have made it simple for researchers to interpret biological processes all by making a small change to the color palette.
In a healthy brain, the multistep waste clearance process known as autophagy routinely removes and degrades damaged cell components - including malformed proteins like tau and toxic mitochondria.
Physicians and scientists have long searched the natural world for chemicals that can improve human health.
Nearly a decade ago, the UN's Food and Agriculture Organization (FAO) developed a new index to assess protein quality in foods. The goal, writ large, was to address food security for the world's most vulnerable populations, creating more accurate tools for food assistance programs seeking to provide balanced nutrition.
A group of scientists from Russia studied the trends in the evolution of amino acid sequences of proteins in vertebrates and insects and traced the factors influencing the process of evolution.
According to a study, failures in a quality control system that defends protein-building fidelity in cells can result in motor neuron degeneration.
SARS-CoV-2 can lead to a broad range of symptoms, from absolutely nothing to multi-organ failure, severe respiratory stress, and eventually death.
Nobel Prize winner Christian Boehmer Anfinsen had demonstrated clearly that a protein is capable of finding its way back to its “native” 3D structure.
