You have an octapeptide that consists of ala, arg, met, gly, pro, cys and ile.
The octapeptide was first treated with pepsin, which resulted in two tetrapeptides, P1 and P2.
P1 was treated with aminopeptidase which resulted in A1 (a single amino acid) and A2 (a tripeptide).
A1 turns yellow in the presence of ninhydrin.
A2 was treated with trypsin which resulted in T1 (a single amino acid) and T2 (a dipeptide).
T2 was treated with carboxypeptidase which released gly and met.
P2 was treated with elastase which resulted in 2 dipeptides, E1 and E2.
E1 was treated with aminopeptidase which released ala and another amino acid.
E2 was treated with carboxypeptidase which released an amino acid and ala.
Based on this information, and your knowledge that may date back to BIOL 190, determine the
amino acid sequence of the octapeptidelind record it as you previously have recorded peptide
sequences using lower case and hyphens in standard peptide equencing format.
