Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.
The structure of a protein that plays a role in importing vitamin B12 into the cells of a tuberculosis (TB)-causing bacterium has been revealed by scientists from the Netherlands, Russia, the United States, and Sweden.
The genetic material, DNA, of plants, animals, and humans is stored inside the cell, and DNA packing is guaranteed by proteins called histones.
Porphyromonas gingivalis is a major bacterial pathogen which leads to periodontitis also known as gum disease. In Japan, 80% of adults aged 35 and over suffer from this disease. What's more, P. gingivalis has also been linked to rheumatoid arthritis, cardiovascular disease, pancreatic cancer, and even Alzheimer's disease.
Revealing the interactions between metal ions and peptides in the body could help develop enhanced treatments for Alzheimer’s diabetes, and other diseases.
Proteins are composed of long chains of amino acids, and a majority of these proteins have one or more methionine—a sulfur-containing amino acid.
A new study reports that cells tend to increase gene expression as a response to physical forces alone. According to the team, the initial step in the production of proteins—gene activation—begins within 1 ms once a cell gets stretched, which is hundreds of times faster than chemical signals can travel.
Chemists from MIT and Harvard University have elucidated the structure of a strange bacterial enzyme with the ability to break down an amino acid found in collagen.
At the University of Tokyo (UTokyo), scientists have identified a new group of proteins that have been hailed for their extraordinary shape and potential to defend against protein clumps linked with neurodegenerative diseases in laboratory experiments.
Researchers have given a new life to the ancient history of two proteins, thus gaining insights into the origin of an age-old molecular partnership.
