DEFINITION

Classification: 424/94.6

Hydrolases (3.) (e.g., urease, lipase, asparaginase, muramidase, etc.):

(under subclass 94.1) Subject matter wherein the enzyme catalyzes the following reaction; AB + H2O=AOH + BH.

(1) Note. The compounds hydrolyzed are usually carboxylic esters, thiolesters, phosphoric esters, sulfuric esters, glycosides, ethers, peptides, amides, amidines, nitriles, acid anhydrides, organic halides, etc.

(2) Note. Peptidases, esterases, glycosidases, and phosphatases are examples of hydrolases.

(3) Note. Examples of the enzymes included here are lipase and ribonuclease.
