In studying the structure of a new enzyme, you find that side chains of Phe, Leu, and Ile are directed into the active site: Which of the following can logically be proposed on the basis of this observation?
a) The substrate for this enzyme is likely to be small.
b) Some groups on the substrate are likely to be hydrophobic.
c) This enzyme is likely to bind its substrate with induced fit to exclude water.
d) The transition state intermediate in the reaction is likely to be small.
