Enzymatic catalysis and transition-state theory.

G E Lienhard

    Science (New York, N.Y.)
    |April 15, 1973
    PubMed
    Summary

    Transition-state theory explains enzyme catalysis by protein-ligand binding strength. Stable transition-state analogs bind enzymes more tightly, showing potential for understanding catalysis and developing chemotherapeutic agents.
