Chorismate mutase is an enzyme that promotes a pericyclic reaction by forcing the substrate to assume the conformation needed for the reaction. The product of the pericyclic reaction is prephenate that is subsequently converted into the amino acids phenylalanine and tyrosine. What kind of a pericyclic reaction does chorismate mutase catalyze?
If a protein were subjected to an acidic solution, which interactions will be disrupted?
(a) Redraw the tripeptide in zwitterionic form
(b) Explain how ESI-MS can be used to determine which amino acid is in the middle of the sequence.
