WebMy lab studies the molecular evolution of enzymes and metabolic pathways. Metabolic enzymes are superb catalysts, accelerating chemical reactions by up to 20 orders of magnitude. Many, and probably all, also catalyze adventitious secondary reactions due to the highly reactive nature of their active sites. WebDNA-editing enzymes perform chemical reactions on DNA nucleobases. These reactions can change the genetic identity of the modified base or modulate gene expression. Interest in DNA-editing enzymes has burgeoned in recent years due to the advent of clustered regularly interspaced short palindromic repeat-associated (CRISPR-Cas) systems, which …

The Design and Application of DNA-Editing Enzymes as Base Editors
WebEnzymes are proteins that significantly speed up the rate of chemical reactions that take place within cells. Some enzymes help to break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. WebApr 11, 2024 · Enzyme reaction kinetics is important to reveal the mechanism of enzyme catalysis and to determine the most efficient reaction system and reaction conditions (Juárez-Enríquez et al., 2024). The study of the effect of MW irradiation on the kinetics of enzyme reactions will contribute to the understanding of the mechanism of changes in … WebA chemical change is one that alters the chemicals in an object to form a new chemical substance. An example of a physical change from the experiment above is paper being ripped into many small pieces. ...
