Analysis of a octapeptide revealed the presence of the following products: 2 Arg, 1 Gly, 1 Met, 1 Trp, 1 Tyr, 1 Phe, 1 Lys The following facts were observed: a. Edman degradation gave: NH b. CNBr treatment yielded a pentapeptide, and a tripeptide containing phenylalanine. c. Chymotrypsin treatment yielded a tetrapeptide containing a C-terminal indole amino acid and two dipeptides d. Trypsin treatment yielded a tetrapeptide, a dipeptide, and free Lys and Phe e. Clostripain yielded a pentapeptide, a dipeptide, and free Phe. What is the amino acid sequence of this octapeptide? (Use the three letter codes for amino acids in your answer, and if there is more than one possible sequence just enter one. Separate amine acids using spaces.)

Considering the general structure of penicillins, how are they rendered ineffective? Select one: O a B-Lactamase performs nucleophilic attack of the amide in the penicillin side chain Ob. B-Lactamase performs nucleophilic attack of the amide in the B-lactam ring and subsequently hydrolyzes this intermediate OC. B-Lactamase performs nucleophilic attack of the thiazolidone ring on the carbon next to the electronegative sulfur leading to a covalently inhibited B-Lactamase o d. All of these O e. None of these
b) Consider the following experimental results: Total hydrolysis of a nonapeptide gave: Ala,Arg, Glu,Leu,Lys,Met,Phe,Tyr,Val One fragment from CNBR treatment was: Tyr-Leu-Lys One fragment from Chymotrypsin treatment was Arg-Glu-Met-Tyr One fragment from Trypsin treatment was Val-Ala-Phe-Arg i. Deduce, with suitable explanations, the amino acid sequence of the nonapeptide.

Phosphoglycerate-mutase catalyses the isomerization of 3-phospho-glycerate to 2-phospho-glycerate. The enzyme has a molecular weight of 28,556 g/mol. In assays using 1 milligram of enzyme per assay the Km for 3-phosphoglycerate was 1.2 x 10^-3M and the Vmax was 840 μmole min^-1. What would be the approximate value of kcat (turnover number or molecular activity) of the enzyme under these conditions?
