ENZYMES: Catalysis, Kinetics and Mechanisms

ENZYMES: Catalysis, Kinetics and Mechanisms by N.S. Punekar.

This enzymology textbook for graduate and advanced undergraduate students covers the syllabi of most universities where this subject is regularly taught. It focuses on the synchrony between the two broad mechanistic facets of enzymology: the chemical and the kinetic, and also highlights the synergy...
