Enzymes are biological catalysts. In simple terms, they speed up chemical reactions. Living organisms have chemical reactions ...

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 ...

Researchers devised a reversibly lockable DNA device for enclosing an enzyme and controlling its access to substrates. Turning on and off the activity of a single enzyme on demand is a much desired ...

New research identifies several existing compounds that block replication of the COVID-19 virus (SARS-CoV-2) within human cells grown in the laboratory. The inhibitors all demonstrated potent chemical ...
