How do allosteric regulation and competitive inhibition compare?
A competitive inhibition and allosteric regulation both involves an inhibitor molecule binding to the enzyme at a different area. The difference between the two is that allosteric inhibitors are modulator molecules which bind somewhere besides the catalytic activity.
What is characteristic of allosteric effectors?
Allosteric effectors may not resemble the enzyme's substrates.
How allosteric enzymes differ non allosteric?
Allosteric enzymes have the ability to change their conformational ensemble after binding. This changes their affinity at a different ligand binding site.
What statement is characteristic of allosteric effectors?
Allosteric effectors may not resemble the enzyme's substrates.
What is the allosteric inhibitor?
The inhibitor which binds or attached with the allosteric site of enzyme k/n as A.I ... BY "NAHEED KHATTI "
What blocks enzyme activity by binding to allosteric site of an enzyme causing the enzyme's active site to change shape?
An allosteric inhibitor stops enzyme activity by binding to an allosteric site and causing the conformation of the enzyme to change.
Some enzymatic regulation is allosteric?
yes
What is allosteric inhibitor of glutamate dehydrogenase?
GTP
What happens during allosteric inhibition?
Allosteric (noncompetitive) inhibition results from a change in the shape of the active site when an inhibitor binds to an allosteric site. When this occurs the substrate cannot bind to its active site due to the fact that the active site has changed shape and the substrate no longer fits. Allosteric activation results when the binding of an activator molecule to an allosteric site causes a change in the active site that makes it capable of binding substrate.
What is Role of allosteric enzyme in regulation of purine synthesis?
if the purine synthesis is excess then extra product will bind to the allosteric site then feed back inhibition occurs
Does the allosteric effect in an enzyme change the enzyme's function?
allosteric effectors have their own specific sites for binding to enzyme. they can bring positiveor negative effect. that depends on the natre of effector.
Allosteric enzymes are most effective when the substrate concentration is?
d
