You Have Isolated a Previously Unstudied Protein, Identified Its Complete

question 30

Multiple Choice

You have isolated a previously unstudied protein, identified its complete structure in detail, and determined that it catalyzes the breakdown of a large substrate. You notice it has two binding sites. One of these is large, apparently the binding site for the large substrate; the other is small, possibly a binding site for a regulatory molecule. What do these findings tell you about the mechanism of this protein?

• A) It is probably an enzyme that works through allosteric regulation.
• B) It is probably a structural protein found in cartilage or skeletal tissue.
• C) It is probably an enzyme that works through competitive inhibition.
• D) It is probably a cell membrane transport protein-like an ion channel.
• E) It is probably a structural protein that is involved in cell- to- cell adhesion.
