General, organic, & biological chemistry

Suggest a name for the enzyme that catalyzes the following reaction.

Analysis

Determine the type of reaction that occurs by examining the functional groups that change. Add the name of the reaction type from Table 21.3 to the name of the substrate.

Table 21.3 Classification of Enzymes
Enzyme Class or Subclass	Reaction Catalyzed
Oxidoreductases	Oxidation–reduction
• Oxidases	• Oxidation
• Reductases	• Reduction
• Dehydrogenases	• Addition or removal of 2 H’s
Transferases	Transfer of a group
• Transaminases	• Transfer of an $\mathrm{NH}_2$ group
• Kinases	• Transfer of a phosphate
Hydrolases	Hydrolysis
• Lipases	• Hydrolysis of lipid esters
• Proteases	• Hydrolysis of amide bonds in proteins
• Nucleases	• Hydrolysis of nucleic acids
Isomerases	Isomerization
Lyases	Addition to a double bond or elimination to give a double bond
• Dehydrases	• Removal of $\mathrm{H}_2 \mathrm{O}$
• Decarboxylases	• Removal of $\mathrm{CO}_2$
• Synthases	• Addition of a small molecule to a double bond
Ligases	Bond formation accompanied by ATP hydrolysis
• Carboxylases	• Bond formation between a substrate and $\mathrm{CO}_2$
