T1, Q1
An enzyme has a mutation within the substrate binding site that
reduces the binding of the coenzyme needed for covalent catalysis.
Which of the following is likely to result as a consequence of this
mutation?
A) The enzyme will function normally
B) The enzyme will use an alternative coenzyme for the reaction
C) The enzyme will no be able to form the transition state complex
D) The enzyme will not be able to bind substrate
Ans: The enzyme will not be able to form the transition state
complex
*Loss of coenzyme binding will result in inability to for m the
transition substrate enzyme complex*
