A fundamental issue in microbial and general ecology is the question to what extent environmental conditions dictate the structure of communities and the linkages with functional properties of ...

Researchers have made a major breakthrough earlier this year in the field of evolutionary conservation of molecular dynamics in enzymes. Their work points to potential applications in health, ...

A wobbly new biochemical structure in one scientist's lab may resemble what enzymes looked like billions of years ago, when life on Earth began to evolve -- long before they became ingredients for new ...

Researchers at Purdue University and The Catholic University of America have discovered the structure of an enzyme essential for the operation of "molecular motors" that package DNA into the head ...

This story is one in a series marking International Women and Girls in Science Day. Join us as we celebrate some laboratory leaders taking research to new heights. Enzymes are the fundamental stuff of ...

Cambridge, MA, November 15, 2012 – A group of researchers at the University of California, Berkeley have for the first time described the structure of the active site core of topoisomerase II alpha, ...

A change in the DNA sequence of a codon may not change the corresponding amino acid residue in the encoded protein because each residue can be encoded by several codons. This is called the Wobble ...

Panel a: This is a cartoon "ribbon" diagram of the structure of Rumi in complex with the donor substrate UDP-Glucose (UDP-Glc, shown in cyan) and acceptor substrate hFA9 EGF (dark green). The spheres ...

The brain relies on a system of chemical messengers, known as neurotransmitters, to carry missives from cell to cell. When all is well, these communications enable the brain to coordinate various ...

Like differently shaped individual beads in a chain, amino acids are joined together to form proteins. The main function of amino acids is to serve as building blocks for proteins. Proteins tend to be ...
