Enzyme Nomenclature Flashcards
Oxidoreductases
oxidation/reduction reactions
Transferases
transfers functional groups
Hydrolases
Cleaves bonds with water
Lyases
breaks double bond to make 2 single bonds
Isomerases
switch molecule from 1 isomer to another
Ligases
uses ATP hydrolysis to form a new bond
Kinase
catcalyzes addition of phosphorylate group to substrate (using ATP as donor)
Phosphatase
catalyze removal of phosphate from substrate
Phosphorylase
catalyze addition of “inorganic” phosphate
Dehydrogenase
catalyze red-ox reactions
requires coenzymes – FAD, NAD+, or NADP+
Hydroxylase
catalyze addition of hydroxyl group
Carboxylase
catalyzes addition of carboxyl group
need coenzyme biotin to hold CO2
Mutase
catalyze movement of funtional group within a substrate
Aldolase
catalyzes reversible condensation of 2 carbonyl (C=O) substrates
