The portion of the enzyme that directly participates in a chemical reaction is called the: oxidoreductases, 1.0 Enzymes that catalyze redox reactions are called: transferases, 2.0 Enzymes that catalyze the transfer of a group (other than hydrogen) from one molecule to another are called: hydrolase...
Enzymes catalyze nearly all of the chemical reactions that occur in biological systems. Enzymes are generally proteins but also include catalytic DNA and catalytic RNA. As effective biological catalysts, enzymes work by lowering a reaction’s activation energy barrier, thereby increasing the rate of th...

Similar mechanisms are likely to be used by enzymes in the HECT E3 family, which also rely on structural flexibility to catalyze multistep reactions. Moreover, conformational rearrangements are important in ubiquitylation enzymes that catalyze one-step reactions, as seen for members of the cullin-...

(dCMP or dCTP) while other possible routes, e.g. the dephosphorylation of dUDP, are considered to be minor supplements4,5,6. When cytosine deamination occurs at the triphosphate level, the resulting dUTP is then converted into dUMP. The enzymes that catalyze these conversions belong to the ...
In contrast to "classical" enzyme engineering, which focuses on optimizing specific properties of natural enzymes, a more recent trend towards the creation of artificial enzymes that catalyze fundamentally distinct, new‐to‐nature reactions is observable. While approaches to create such enzymes differ ...
Enzymes are biological catalysts, i.e., they catalyze reactions in animal and plant tissue that, if performed in vitro , would proceed at a very slow rate or would require more drastic conditions to reach a velocity equivalent to those observed in cells. Enzyme-catalyzed reactions take place ...
