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 ...

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 ...

Inside cells, two important enzymes act like small central regulatory hubs: dipeptidyl peptidase 8 and 9—DPP8/9 for short.

Enzymes are able to bind to their substrate because they have an active site. An induced fit occurs where the active site of the enzyme is changed slightly to better fit the substrate after the ...

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

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 ...

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 ...

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