Enzymes 2 Flashcards
Naming of Enzymes
adding the suffix “-ase” to the:
- name of their substrate
- word/phrase describing activity
(ex. urease - catalyzes hydrolysis of urea)
discoverers for a broad function, before the specific reaction catalyzed was known. (pepsin from greek word pepsis that means digestion)
What are the seven classes for naming and classifying enzymes?
Oxidoreductases
Transferases
Hydrolases
Lyases
Isomerases
Ligases
Translocases
which class of enzymes catalyzes transfer of electrons?
oxidoreductases
which class of enzymes catalyzes group transfer?
Transferases
which class of enzymes catalyzes hydrolysis?
Hydrolases
which class of enzymes catalyzes cleavage of C-C, C-O, C-N, or other bonds by elimination, leaving double bond or rings, or addition of groups to double bonds
Lyases
which class of enzymes catalyzes transfer of groups within molecules to yield isomeric forms?
Isomerases
which class of enzymes catalyzes formation of C-C, C-N, C-O bonds by condensation reactions coupled to cleavage of ATP or similar cofactor?
Ligases
which class of enzymes catalyzes movement of molecules or ions across membranes or their separation within membranes?
Translocases
transfer of functional groups to water
hydrolysis
What is being catalyzed by Oxidoreductase?
Transfer of electrons
What is being catalyzed by Transferases?
group transfer
What is being catalyzed by Hydrolases
hydrolysis
What is being catalyzed by Lyases?
cleavage of C-C, C-O, C-N, or other bonds by elimination, leaving double bonds or rings, or addition of groups to double bonds
What is being catalyzed by Isomerases?
Transfer of groups within molecules to yield isomeric forms
