Question 4 (14 pts). A scientist is trying to determine the sequence of a pentapeptide antibiotic. ) amino acid composition analysis shows the peptide to contain Arg, lle, Met, Tyr and Gly I) incubation with trypsin gives a dipeptide and a tripeptide III) incubation with cyanogen bromide also gives a dipeptide and a tripeptide IV) incubation with chymotrypsin has no effect. V) A single round of Edman degradation on the tryptic dipeptide gives the PTH derivative for Gly 4A (10 pts). In one-letter code, list any pentapeptide sequence that is consistent with the above data, and draw arrows labeled "trypsin" and "cyanogen bromide" to appropriate cleavage points.
