Scientists have developed a simple two-molecule chemical analogue of an enzyme and its substrate that neatly illustrates the fundamental principles of biological catalysis. The reaction provides a ...

Different keys are not supposed to fit the same lock, but in biological systems multiple versions of a catalyst all make a reaction go, according to a new study that explains the phenomenon. The study ...

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are essential for life, as they play a crucial role in various biological processes, such as digestion, ...

CHAPEL HILL -- All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds. But how slowly would these ...
