Amino acids are the fundamental building blocks of proteins and play central roles as intermediates in myriad metabolic pathways. In medical biochemistry, they are not only recognised for their ...

Two new options for making designer proteins made news in 2001—both from labs at Scripps Research Institute. Since 2001, Schimmel and Schultz have taken different directions with unnatural amino acids ...

Proteins are the molecular machines that make all living things hum. They stop deadly infections, heal cells, capture energy from the sun and so much more. Proteins are built by stringing together ...

The molecular machines that cells use to build proteins are backed by a billion years of evolution. In that time, these machines—ribosomes—have become exceptionally good at forging amide bonds between ...

In a new peer reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor is the single life form that branched into ...

Advanced Chemistry of Catalonia (IQAC) of the Spanish National Research Council (CSIC), an institution under the Ministry of ...

Plant Physiology, Vol. 146, No. 3 (Mar., 2008), pp. 1028-1039 (12 pages) In Arabidopsis thaliana, transamination steps in the leucine biosynthetic and catabolic pathways and the methionine (Met) chain ...

Search “best supplements for women” and you’ll likely find a list dominated by vitamins and minerals. And while these micronutrients are critical, there’s another supplement category equally important ...

In a discovery fundamental to the inner workings of cells, scientists have discovered that if oxidative stress damages protein factories called ribosomes, repair crews may move in to help fix the ...

Using data from the Spitzer space observatory, Dr. Susana Iglesias-Groth, a researcher from The Instituto de Astrofísica de Canarias (IAC), has found evidence for the existence of the amino acid ...
