1Purpose of hydrolases?
catalyze hydrolytic cleavage rx
2Two common types of hydrolases:
(nucleases and proteases are a type)
3Purpose of proteases?
break down proteins by hydrolyzing bonds between amino acids
4Purpose of synthases?
synthesize molecules in anabolic reactions by condensing two smaller molecues together
5Purpose of Ligases?
join together two molecules in an energy dependent way
6One ex of a ligase?
-DNA ligase
7What do isomerases do?
catalyze the rearrangement of bonds within a single molecule
8What do polymerases do? provide an ex
catalyze polymerization of reactions, ex DNA and RNA
9Purpose of Kinases?
catalyze additon of phosphate groups to molecules
10What do protein kinases do?
attach phosphate groups to proteins
11Purpose of phosphatases?
-catalaze hydrolytic removal of phosphate group from a molecule
12What are oxido-reductases? three common names
enzymes that catalyze rx here one molecule is oxidized while the other is reduced (oxidases, reductases, hehydrogenases)
13Purpose of ATPases?
hydrolyze ATP, found on many proteins
14In what processes would ATPase be found?
-motor proteins (myosin)
-transport proteins (Na-K pump)
15What do GTPases do?
-hydrolyze GTP
16What factors influence enzyme activity?
PH, temp, substrate concentration, regulation
17Role of disulfide isomerases?
e key players in ensuring that enzymes fold properly and maintain their structural integrity (stabilize active sites, help revent misfolding)
