This work offers a timely synopsis of advanced DG understanding of enzymatic regulation and function. Chapters are authored Y F by both those in traditional protein studies and those challenging paradigms, U N bridging disconnected fields, and presenting a unified view of enzyme C mechanisms. Biochemists, structural biologists, and other researchers T I O working with enzymes will find this work useful. Each chapter is written to N maximize accessibility to students and bridge developed theory with current scientific literature. This work serves as a valuable teaching tool to introduce foundational topics to students, bridging distantly connected fields toward the presentation of a unified view of enzyme mechanism.
