question 37

Multiple Choice

What is the defining characteristic of an allosteric protein?

• A)They contain two polypeptide chains,with each being an exact mirror image of the other.
• B)They contain only one ligand-binding site,but because the specificity is low,many different ligands can bind to it.
• C)They contain two ligand-binding sites,one that activates the protein when a ligand binds,and the other that inactivates the protein when the same ligand binds.
• D)They contain more than one ligand-binding site,and noncovalent binding of a ligand to one site alters the shape of other ligand-binding sites.
• E)They contain no binding sites of their own,but act by modulating the activity of other proteins.
