5: Enzyme Catalysis and Kinetics

  • Page ID
    • 5.1: Introduction
      In this chapter, we look at the properties and mechanism of action of enzymes. These include allosteric change (induced fit, enzyme regulation), energetic events (changes in activation energy), and how enzymes work in open and closed (experimental) systems. Any catalyst, by definition, accelerates a chemical reaction. But enzymes and inorganic catalysts differ in important ways (blue and red in the table below).
    • 5.2: Enzymes
      By 1941, their studies correlating mutations with enzyme deficiencies in Neurospora crassa (bread mold) and Drosophila melanogaster led George Beadle and Edward Tatum to propose the one-gene/one-enzyme hypothesis in 1941. In 1958, they shared Nobel Prize in Physiology and Medicine for this work.
