Protonated side chain in an enzyme’s active site

  • acts as a nucleophile during catalysis
  • can mimic the reactivity of a metal ion
  • can donate a proton during catalysis

Enzymes accelerates a chemical reaction by

  • giving energy to the reacting molecules
  • increasing the activation energy of the system
  • harnessing thermal energy to promote electron rearrangements
  • making it easier for reactants to reach the transition state

Enzyme that carries out metal ion catalysis

  • includes a cofactor
  • is a prosthetic group
  • has a chemical label
  • lacks an active site
