Complementary biochemical and structural findings reveal molecular principles underlying substrate selectivity by a model hyaluronan synthase.

For over 350 years, quinine and other extracts from the cinchona tree (Cinchona spp.) were the only effective medicines ...

By reconstructing ancient nitrogen-processing enzymes, scientists are uncovering new clues about how early life survived on a very different Earth.

A metabolic enzyme studied for over seven decades has a hidden second function—it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, ...

Reaction kinetics and dynamics refers to the study of why, how and how fast chemical processes take place. Chemists seek to understand the details of change at the molecular and quantum level and how ...

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules such as nucleic acids and proteins that carry out the biological processes ...
