Allosteric enzymes do not obey Michaelis-Menten kinetics; they exhibit a curve.

This edition was published at a particularly pivotal time, soon after the rapid acceleration in the structural characterization of enzymes and the emergence of the field of bioinformatics. The book intentionally weaves these modern concepts with established principles, creating a rich understanding of how proteins function as molecular machines.

The same review confirmed its practical value across academic levels, noting it "remains an extremely useful textbook for undergraduate students and their teachers of enzymology and is a useful reference work for postgraduate students embarking on research in this area."

Upon its release, the third edition was met with significant praise, recognized for its timely and valuable contribution to the field during a renaissance in enzymology. A review in the journal Trends in Biochemical Sciences highlighted its broad utility, stating:
