Enzymes are chemically changed by a reaction

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 …
