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 ...

A bacterial enzyme could make it possible to produce the plastic building block ethylene without the emission of CO₂.

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 ...

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 ...

Gene editing is one of the latest breakthroughs in biology. The widely known CRISPR-Cas gene editing system provided prokaryotes (organisms that lack cell nuclei) an immunity against foreign DNA.

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 ...

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 ...

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 ...
