Every enzyme has a place in which the molecule fits exactly. This is known as the active site. The active site of the catalase allows the hydrogen peroxide molecule to fit exactly. You could say ...

Inside cells, two important enzymes act like small central regulatory hubs: dipeptidyl peptidase 8 and 9—DPP8/9 for short. Among other things, they regulate inflammatory reactions and influence ...

Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits. The substrate goes through a chemical reaction and changes into a new molecule ...

Figure 1. Structure of the active sites in [NiFe]-hydrogenase, [FeFe]-hydrogenase, and [Fe]-hydrogenase Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases ...

Scientists discovered that a key shift in enzyme function occurred over evolutionary time due to amino acid changes distant from the active site. These mutations lowered activation energy ...

Enzymes have active sites which only match specific substrates. The diagram shows how this works. In this example, the enzyme splits one molecule into two smaller ones, but other enzymes join ...

Now, researchers from Waseda University and RIKEN in Japan have shown that key evolutionary changes in enzyme function were driven by amino acid substitutions located far from the active site ...

Similarly, enzymes—proteins that speed up biochemical ... Surprisingly, these mutations occurred far from the active site, challenging the previous belief that temperature adaptation is ...

Since enzymes are quite efficient biocatalysts active under mild conditions, they are expected to be applied to varieties of environmentally benign chemical processes realized in the next generation.
