Question

ou 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 bonding 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

Answer 1

These findings tell us that possibly this protein has an enzymatic function, that is, it is an enzyme.

Its function can be catalytic as well as analytical.

The substrate binding site should be the largest, while the other regulatory site is the smallest.

Step-by-step explanation:

This happens since hormones regulate their enzymatic activity through inhibitory sites.

They have another smaller binding site, where when an inhibitory molecule binds, it deforms the morphology of the protein causing it to no longer bind to its substrate at the binding site, therefore they inhibit the chemical reaction that is happening within the enzyme. both catalytic and analytical.
