Question:

The active site of the enzyme Ritzolinine (RZN45) contains three positively charged lysine residues. When ascorbic acid is present, binding of JB-76, the substrate of RZN45, decreases. The reaction rate is affected by the presence of ascorbic acid as shown in the figure below. It is thought that a daily supplement of Vitamin C might aid those suffering from Ritzolierre's Disease, which is caused by elevated levels of RZN45.Reaction Rate X Ascorbic Acid Present ---- Normal Concentration of JB-76

Which of the following is likely true?
(A) RZN45 and JB-76 have similarly charged amino acids at their active sites.
(B) Ritzolinine is stabilized in the presence of Vitamin C.
(C) Ascorbic acid and JB-76 each have a pocket of negatively charged amino acids.
(D) JB-76 and ascorbic acid have an identical number of amino acids.
