Hydrolase

In biochemistry, a hydrolase or hydrolytic enzyme is an enzyme that catalyzes the hydrolysis of a chemical bond. For example, an enzyme that catalyzed the following reaction is a hydrolase:

A–B + H2O → A–OH + B–H

Nomenclature

Systematic names of hydrolases are formed as "substrate hydrolase." However, common names are typically in the form "substratease." For example, a nuclease is a hydrolase that cleaves nucleic acids.

Classification

Hydrolases are classified as EC 3 in the EC number classification of enzymes. Hydrolases can be further classified into several subclasses, based upon the bonds they act upon:

Clinical considerations

Hydrolase secreted by Lactobacillus jensenii in the human gut stimulates the liver to secrete bile salts that aids in the digestion of food.[1]

Etymology and pronunciation

The word hydrolase (/ˈhaɪdroʊleɪs, -leɪz/) suffixes the combining form of -ase to the hydrol syllables of hydrolysis.
