Enzymes catalysis
WebRecall from Chapter 6, that enzymes are biological catalysts that reduce the activation energy required for a reaction to proceed in the forward direction (Figure 7.1). They facilitate the formation of the transition state … WebCovalent catalysis. Metal ion catalysis. b and d. a, b & d. Suppose that the covalent catalytic mechanism of an enzyme depends on a single active site amino acid (Cys), whose pKa = 8.3. A mutation in a nearby amino acid residue of the enzyme only slightly alters the microenvironment so that the pKa of the Cys residue increases to 10.3.
