! |[[List of EC numbers (EC 1)|EC 1]]<br />''[[Oxidoreductase]]s''
| To catalyze [[oxidation]]/reduction reactions; transfer of H and O atoms or [[electron]]s from one substance to another
| AH + B → A + BH (<small>'''reduced'''</small>)<br /> A + O → AO (<small>'''oxidized'''</small>)
| [[Dehydrogenase]], [[oxidase]]
|-
! [[List of EC numbers (EC 2)|EC 2]]<br />''[[Transferase]]s''
| Transfer of a [[functional group]] from one substance to another. The group may be methyl-, acyl-, amino- or phosphate group
| AB + C → A + BC
| [[Transaminase]], [[kinase]]
|-
! [[List of EC numbers (EC 3)|EC 3]]<br />''[[Hydrolase]]s''
| Formation of two products from a substrate by [[hydrolysis]]
| AB + H<sub>2</sub>O → AOH + BH
| [[Lipase]], [[amylase]], [[peptidase]]
|-
! [[List of EC numbers (EC 4)|EC 4]]<br />''[[Lyase]]s''
| Non-hydrolytic addition or removal of groups from substrates. C-C, C-N, C-O or C-S bonds may be cleaved
| RCOCOOH → RCOH + CO<sub>2</sub> or [X-A-B-Y] → [A=B + X-Y]
| [[Decarboxylase]]
|-
! [[List of EC numbers (EC 5)|EC 5]]<br />''[[Isomerase]]s''
| Intramolecule rearrangement, i.e. [[isomer]]ization changes within a single molecule
| ABC → BCA</td>
| [[Isomerase]], [[mutase]]
|-
! [[List of EC numbers (EC 6)|EC 6]]<br />''[[Ligase]]s''
| Join together two molecules by synthesis of new C-O, C-S, C-N or C-C [[covalent bond|bonds]] with simultaneous breakdown of [[Adenosine triphosphate|ATP]]
| X + Y+ ATP → XY + ADP + Pi
| [[Synthetase]]
