hydro-lyase activity

Definition

Target type: molecularfunction

Catalysis of the cleavage of a carbon-oxygen bond by elimination of water. [EC:4.2.1.-]

Hydro-lyase activity refers to the ability of an enzyme to cleave a molecule into two or more smaller molecules by breaking a chemical bond without the addition of water. This process typically involves the formation of a new double bond or a ring structure. Hydro-lyases are distinguished from hydrolases, which utilize water to break bonds. The cleavage reaction often occurs between carbon-carbon, carbon-oxygen, carbon-nitrogen, or carbon-sulfur bonds. These enzymes play crucial roles in various biological processes including metabolism, biosynthesis, and detoxification. Some common examples of hydro-lyases include aldolases, decarboxylases, and lyases involved in the breakdown of carbohydrates, amino acids, and other biomolecules.'
