Researchers have made a significant advance toward the goal of using bacteria—rather than fossil fuels—to produce ethylene, a ...

Researchers have used cryo- electron microscopy to elucidate for the first time the structure and function of a very small enzyme embedded in cell membranes. This enzyme builds complex sugar trees ...

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 ...

The structure of enzymes determines how they control vital processes such as digestion or immune response. This is because the protein compounds are not rigid, but can change their shape through ...

The enzyme transhydrogenase plays a central role in regulating metabolic processes in animals and humans alike. Malfunction can lead to serious disorders. For the first time, structural biologists ...

Background and aims Aluminum is a major deleterious factor for soybean productivity in acidic soils. Soil enzyme activities and bacteria play important roles in improving the stress tolerance of ...

Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or “ribozyme,” that carries out a fundamental reaction required to make new ...

There's a wobbly new biochemical structure in Burckhard Seelig's lab at the University of Minnesota that may resemble what enzymes looked like billions of years ago, when life on earth began to evolve ...

Researchers used cryo-EM to study how the HIV enzyme integrase arranges in 3D to slip its DNA into the host genome and pack ...

Most drugs operate via the membranes that surround the body's cells. A study by researchers at Karolinska Institutet in Sweden has now mapped the structure and mechanism of MGST2, a membrane enzyme ...
