'Enzyme Classes'
Enzyme classification and discription
| Enzyme Class/Subclass | Details |
|---|---|
| Hydrolase Action | Cleaves by hydrolysis |
| Hydrolase subclasses | Esterase Lipase Peptidase Phosphatase |
| Esterase | Hydrolyzes ester to form alcohol + acid |
| Lipase | Hydrolyzes ester of fatty acids and glycerols |
| Peptidase | hydrolyzes peptide bond |
| Phosphatase | Hydrolyzes esters of phosphdiesters results in inorganic phosphate |
| Isomerase action | form one isomer from another ex. aldehyde --> ketone |
| Isomerase subtypes | Mutase Racemase |
| Mutase | shifts group from one place to another (isomerase) |
| Racemase | changes chiral molecules to its mirror image form (isomerase) |
| Ligase action | joins two molecules always couple with ATP hydrolysis |
| Ligase subtypes | Carboxylase Synthetase |
| Carboxylase | links molecule with CO2 (ligase) |
| synthetase | links two molecules together (ligase) |
| Lyase action | Forms or breaks molecules between C-O C-C or C-N bond |
| Lyase subtypes | Hydratase Synthase |
| Hydratase | Uses water to break/form C-O bond (lyase) |
| Synthase | Creates or breaks C-C w/o ATP (lyase) |
| Oxidoreductase action | catalyze oxidation/reduction rxns |
| Oxidoreductase subtypes | Dehydrogenase Desaturase Oxidase Reductase |
| Dehydrogenase | Oxidizes substrate by transferring H (o.r.tase) |
| Desaturase | desaturates molecule (o.r.tase) |
| Oxidase | Oxidizes using molecular Oxygen |
| Reductase | Reduces by transferring H |
| Transferase action | Transfers group other than H |
| Transferase subtypes | Kinase Phosphorylase Transaminase |
| Kinase | transfers high energy group (usually P) |
| Phosphorylase | Adds Pi to break C-O bond |
| Transaminase | transfers amino group from amino acid to alpha-keto acid |
