Living things, from bacteria to humans, depend on a workforce of proteins to carry out essential tasks within their cells. Proteins are chains of amino acids that are strung together according to ...
Researchers from UNIGE and Marburg show that D-cysteine, the "mirror" form of cysteine, selectively targets certain cancer ...
How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As, Cs, ...
Humans possess six forms of the protein actin, which perform essential functions in the body. Two in particular, β-actin and γ-actin, are nearly identical, only differing by four amino acids. Yet ...
The findings, which detail how amino acids shaped the genetic code of ancient microorganisms, shed light on the mystery of how life began on Earth. "You see the same amino acids in every organism, ...
Membrane proteins play important roles in health and disease, but they are so hydrophobic that they require detergents to maintain their shape outside membranes. That makes them difficult to study.
With only rare exceptions, every organism constructs proteins from just 20 building blocks called amino acids. Recently, however, researchers modified Escherichia coli bacteria so that the ...
To reveal the structural principles determining substrate specificity of 4-coumarate:CoA ligase (4CL), the crystal structure of the phenylalanine activation domain of gramicidin S synthetase was used ...
Proteins are the workhorses that keep our cells running, and there are many thousands of types of proteins in our cells, each ...
High homocysteine levels, or hyperhomocysteinemia, may indicate that a person has a deficiency in specific vitamins. Experts also associate hyperhomocysteinemia with a higher risk of cardiovascular ...
The genetic code is a set of rules defining how the four-letter code of DNA is translated into the 20-letter code of amino acids, which are the building blocks of proteins. The genetic code is a set ...
