enzymes Flashcards
what are enzymes
protein catalyst, that increase the rate of reaction without being change in the overall process
name the two type of nomenclature of enzyme
recommended name
systemic name
the short and convenient for everyday use this type nomenclature is
recommended nomenclature
more complete, which is used when an enzyme must be identified without ambiguity
systematic nomenclature
most used suffix in enzymes in recommended names and give one eg
-ase,
glucosidase, urease
give example of enzymes that includes action in names
lactate dehydrogenase (LDH)
adenylyl cyclase
name the enzyme retain their original trivial name
trypsin pepsin
what are the six major classes in systemic nomenclature
- oxidoreductase
- transferase
- hydrolase
- lyases
- isomerase
- ligase-
action of oxidoreductases enzymes
catalyzes oxidation-reduction reaction
the catalyze that transfer of C-, N-, or P- containing groups
tranferase
what is the action of isomerase
catalyzes rearrangement of optical or geometric isomerases
catalyze cleavage of bonds by addition of water
hydrolases
catalyze formation of bonds between carbon and O, S and N coupled to hydrolysis of high-energy phosphates are
ligases
what is the action of lyases
cleavage of C-C, CS, and certain
some RNAs can catalyze reactions that affect
phosphodiesters and peptide bonds
