Verified step by step guidance1
Examine the chemical reaction catalyzed by the enzyme arginase. The reaction involves the conversion of L-arginine into L-ornithine and urea, with water as a reactant.
Identify the type of chemical transformation occurring in the reaction. The reaction involves the cleavage of a bond in L-arginine, resulting in the formation of urea and L-ornithine.
Recognize that the reaction involves the addition of water to break a bond, which is characteristic of hydrolysis reactions.
Understand that enzymes that catalyze hydrolysis reactions are classified as hydrolases. Hydrolases facilitate the breaking of chemical bonds through the addition of water.
Conclude that the enzyme arginase, which catalyzes the hydrolysis of L-arginine to produce L-ornithine and urea, is classified as a hydrolase.
