|
To catalyze oxidation/reduction reactions; transfer of H and O atoms or electrons from one substance to another |
AH + B → A + BH (reduced) |
||
|
Transfer of a functional group from one substance to another. The group may be methyl-, |
AB + C → A + BC |
||
|
Formation of two products from a substrate by hydrolysis |
AB + H2O → AOH + BH |
||
|
Non-hydrolytic addition or removal of groups from substrates. |
RCOCOOH → RCOH + CO2 or [X-A+B-Y] → |
||
|
Intramolecule rearrangement, i.e. isomerization changes within a single molecule |
ABC → BCA |
||
|
Join together two molecules by synthesis of new C-O, C-S, C-N |
X + Y + ATP → XY + ADP + Pi |
||
|
Catalyse the movement of ions or molecules across membranes or |
The 7. Class was only recently added. This “Translocation” across membranes is much needed category in Enzymology. The other classes are on the reaction steps with substrate. The phases separated by membranes is need for the translocation class.
