Enzymes Flashcards
Enzymes that catalyze oxidation-reduction reaction
Oxidoreductases
Enzymes that transfer functional groups
Transferases
Enzymes that catalyze hydrolysis reactions
Hydrolases
Enzymes that isomerize a substrate
Isomerases
Enzymes that eliminate groups to form double bonds or add to a double bond
Lyases
Enzymes that form bonds coupled with ATP hydrolysis to provide energy
Ligases
What are the 6 denaturing agents?
Heat Agitation Detergents Organic solvents Acids or bases Inorganic salts
How does adding acid, base, or nonpolar solvent denature proteins?
Acid or base changes charges on acidic or basic side chains and disrupts salt bridges
Nonpolar solvents disrupt hydrophobic interactions.
What are the interactions that hold primary structures together?
Peptide bonds
What interactions form secondary structure?
Hydrogen bonds along the backbone, irrespective of R groups
What 5 types of interactions form tertiary structure?
Interactions between R groups: Hydrogen bonds Hydrophilic interactions Ionic/salt bridges Hydrophobic interactions Disulfide bridges
