Researchers have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction required to make new RNA molecules. Their results provide insight ...

UPTON, NY—Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have produced the first atomic-level structure of an enzyme that selectively cuts carbon-hydrogen bonds—the first ...

A research team has solved the crystal structure for an enzyme that plays a key role in DNA methylation, the process by which methyl groups are added to the DNA molecule. The breakthrough reveals how ...

Viruses can enter the body via a number of pathways and while scientists have known how to block the main one used by viruses such as HIV, Hepatitis C, Dengue Fever and West Nile virus for some time, ...

Researchers have made a significant advance toward the goal of using bacteria—rather than fossil fuels—to produce ethylene, a key chemical in the production of many plastics. Subscribe to our ...

WEST LAFAYETTE, Ind. - Purdue researchers have discovered the structure of the enzyme that makes cellulose, a finding that could lead to easier ways of breaking down plant materials to make biofuels ...

Malathy Palayam, Aleczander Young, Lior Tal, and Nitzan Shabek at the UC Davis Department of Plant Biology are exploring the mechanism by which the plant hormone strigoractone regulates a massive ...

The latest short science news items from C&EN. The team proposes that SAM plays a dual role in the reaction. It donates a methyl group to the enzyme’s cobalamin cofactor and then serves as a base when ...

Figure 1: Sample transformations of metabolites from their ground state structure into the high-energy intermediate forms that were used for docking. What is clear is that Tm0936 has orthologues ...

Current demand for plastics and chemical raw materials is met through large-scale production of ethylene from fossil fuels. This makes it necessary to search for new, renewable processes. Using ...
