From the given table, the amino acid sequence that would be an effective reagent for sequencing the protein with chymotrypsin is to be identified and the reason for its effectiveness is to be explained. Concept introduction: Before the sequencing experiment of the proteins is carried out, the peptides are initially converted into small length peptides by the action of certain chemicals or enzymes. These enzymes cut the proteins at specific points, to yield smaller fragments of peptides. Examples of such chemicals or enzymes are trypsin, chymotrypsin, and cyanogen bromide. The reagent cyanogen bromide cleaves the protein peptides at their internal methionine residues. The proteolytic enzyme chymotrypsin cleaves the protein peptides at the sites where the aromatic amino acid (tryptophan, tyrosine, and phenylalanine) residues are present.

The beta-lactamase hydrolyzes the lactam-ring in penicillin. Describe the mechanism of hydrolysis, insuring to include the involvement of S, D, & K in the reaction sequence. Please help

To map the active site of beta-lactamase, the enzyme was hydrolyzed with trypsin to yield a hexapeptide (P1) with the following amino acids. Glu, Lys, Leu, Phe, Met, and Ser. Treatment of P1 with phenyl isothiocyanate yielded a PTH derivative of phenylalanine and a peptide (P2). Treatment of P1 with cyanogenbromide gave an acidic tetrapeptide (P3) and a dipeptide (P4).Treatment of P2 with 1-fluoro-2,4-dinitrobenzene, followed by complete hydrolysis, yields N-2,4-dinitrophenyl-Glu. P1, P2, and P3 contain the active site serine. Why doesn't D in this hexapeptide not participate in the hydrolysis of the beta-lactam ring even though S, K, and D are involved in the catalyst?
