M5 - Lesson 2: Classification of Enzymes Flashcards
6 Classes / Examples Reaction Catalyzed
Hydrolases Oxidoreductases Transferases Lyases Isomerases Ligases
Most Common Enzymes that catalyze hydrolysis reactions.
Hydrolases
Enzymes that catalyze oxidation-reduction reactions.
Oxidoreductases
Enzymes that catalyze reactions involved in the trasfer of functional groups.
Transferases
Enzymes that catalyze the elimination of groups to from double bonds.
Lyases
Enzymes that catalyze the interconversion of isomers.
Isomerases
Enzymes that, in conjuction with ATP, catalyze the formation of new bonds.
Ligases
Enzymes that substrates and acts as bond of Hydrolases.
Carbohydrates
Esterases
Proteases
Nucleases
Catalyzes Hydrolysis and Adding water to a complex substance; Polysaccharides + H2O → Monosaccharides + Disaccharides
Carbohydrates
Catalyzes Hydrolysis and Adding water to a complex substance; Ester + H2O → Carboxylic acid + alcohol
Esterases
Catalyzes Hydrolysis and Adding water to a complex substance; Protein + H2O → Peptides + amino acid
Proteases
Catalyzes Hydrolysis and Adding water to a complex substance; Nucleic acids + H2O → Pyrimidines/ purines + sugars + phosphoric acid
Nucleases
