Homework Answers
The reaction is an example of "acid base catalysis".
As you can see above in mechanism that first step involve the "alcohol" (-O---H) group as catalyst.
The only amino acid which have alcohol group as a side chain is "Serine".
Hence, correct option is : serine

While the oxygen and nitrogen atoms of the peptide bonds may serve as a donor atom to complex a metal ion, very often the ligands for the metal come from the amino acid side chains. Takea few moments to examine the chemical structures of the different side chains. Circle the side chains that you...
