Enzymes are biological catalysts that lower the activation energy of chemical reactions, allowing them to proceed at a faster rate. This illustration depicts the process of enzyme catalysis. The ...

Enzymes lower the activation energy necessary to transform a reactant into a product. On the left is a reaction that is not catalyzed by an enzyme (red), and on the right is one that is (green).

Figure 1: Active site structures of representative nonheme iron enzymes with a 2-His-1-carboxylate facial triad and the reactions they catalyze. A comparison of the primary sequence information of ...

Enzymes in metabolic pathways are superb catalysts, accelerating chemical reactions by up to 16 orders of magnitude. Many enzymes also catalyze adventitious secondary reactions, simply because active ...

However, it is safe to say that no enzyme is perfect in the sense of catalyzing only a single reaction with a single substrate. For enzymes such as P450s and glutathione S-transferases that are ...

Others are protein molecules, called enzymes, that are contained in microorganisms. Still others are naturally occurring solids, such as manganese or iron ixides. No matter what the catalyst's ...

This study has the potential to revolutionize our understanding of enzyme catalysis and evolution." This research, now ...
