these enzymes catalyze hydrolisis reactions Examples: ester, amide (peptide), glycosidic, and phosphate bonds are hydrolyzed by hydrolase enzymes Enzymes such as lipases (esterases), peptidases, amylases, and phosphatases are hydrolase enzymes

these enzymes catalyze intramolecular transformations such that one molecule is converted to one of its isomers in carbohydrate metabolism, enzymes such as epimerase and mutase are involved

these enzymes catalyze formation of bonds between carbon and other atoms, primarily nitrogen, oxygen, and sulfur Enzymes such as synthases, are ligase enzymes In more general terms, ligation or ligase reaction refers to a synthesis reaction

these enzymes catalyze breakage of carbon-carbon, carbon-sulfur, and carbon-nitrogen bonds (but not peptide bonds) Reactions in which CO2 groups are removed, carbon chains are shortened, or hydroxy groups are removed are catalyzed by lyases

these enzymes catalyse oxidation (loss of a H+) and reduction (gain of a H+) reactions. Many reactions involve numerous steps to produce the desired products Very often oxidation and reduction reactions are part of these reaction sequences Enzymes known as dehydrogenases are common examples of oxidoreductases

as the name implies, these enzymes catalyze transfer of certain funcitonal groups from one molecule to another Acyl-, amino-, carbonyl-, carboxyl-, mehtyl-, and phosphoryl- transferases are common in cellular metabolism
