Hydrolases-These enzymes catalyze hydrolysis reactions. Examples are the digestive enzymes such as sucrase, amylase, maltase, and lactase. These enzymes catalyze the removal of groups in non-aqueous media. An example would be the decarboxylases. Enzymes that catalyze the isomerization of molecules.
Examples are racemases, and cis-trans isomerases.
These are also called synthetases which are enzymes that catalyze condensation reactions where smaller molecules are connected with the resulting removal of a water molecule. This is accompanied with the formation of a high energy Phosphate link that stores energy. An example would be the amino acid RNA ligases. In addition to the classification name most enzymes have group names. Hydrolases-Enzymes that catalyze hydrolysis reactions.
