What is the site of oxygen binding on hemoglobin?
You have Iron atoms in hemoglobin. This atom is the binding site for oxygen in case of hemoglobin.
Which molecule has a binding site for calcium?
Calmodulin is a calcium-binding protein that has a binding site for calcium ions. It is involved in the regulation of various cellular processes by binding calcium and transducing the signal to downstream effectors.
Which molecule covers the binding site?
Proteins can cover the binding site of a receptor and prevent another molecule from binding to it. This interaction can inhibit the receptor's activity and affect cellular signaling pathways.
What Is the difference between antigen binding site and paratope?
Antigen binding site or epitope is a part of an antigen that is recognized by the antibody. Paratope is a part of an antibody that binds on epitope.
What is the difference between an allosteric enzyme and a non-allosteric enzyme?
An allosteric enzyme has multiple binding sites that can be used to modulate its activity through the binding of effectors or ligands, whereas a non-allosteric enzyme typically only has one active site. Allosteric enzymes can exhibit cooperativity, meaning that binding at one site affects binding at another site, while non-allosteric enzymes do not show this behavior.
To which specific site on a protein does the ligand attach?
The ligand attaches to a specific site on a protein called the binding site.
The region of a protein that binds a ligand?
The region on a protein that binds a ligand is known as the binding site. This site is typically composed of specific amino acids that interact with the ligand through various chemical bonds and molecular interactions. The binding of the ligand to the protein's binding site is crucial for the protein's function and activity.
Difference between active site and binding site?
Binding site is anywhere which something (such as a protein) can bind to. An example would be the upper flanking regions which contain binding sites thattranscription factors bond with during transcription. The active site is more specific to enzymes and refers to the site where the enzyme functions. It is the specific contours of this active site which give the enzyme its specific function (see how enzymes are substrate specific).
Which blocks enzyme activity by binding to the site of an enzyme?
inhibitor
What is the region on an enzyme to which a substrate bind is called?
Binding site.
How do allosteric regulation and competitive inhibition differ in their mechanisms of enzyme regulation?
Allosteric regulation involves a molecule binding to a site on the enzyme that is not the active site, causing a change in the enzyme's shape and activity. Competitive inhibition involves a molecule binding to the active site of the enzyme, blocking substrate binding and enzyme activity.
What blocks enzyme activity by binding to allosteric site of an enzyme causing the enzyme's active site to change shape?
Allosteric inhibitors bind to a specific site on an enzyme (allosteric site) other than the active site, inducing a conformational change that decreases enzyme activity. This alteration prevents the substrate from binding to the active site, thus blocking the enzyme's ability to catalyze reactions.
