After incubation with fdnb and hydrolysis, 2,4‑dinitrophenylalanine was detected. amino acid alanine with 2 4 dinitro benzene attached to the amino group. treatment with cyanogen bromide, which cleaves at m, resulted in two fragments: a pentapeptide containing two k residues and a tripeptide containing v, g, and a. the residues are not listed in any particular order. after treatment with trypsin, which cleaves at r and k, there were three fragments: two dipeptides and mgav. what is the sequence of the octapeptide? use the one‑letter abbreviations for the amino acids, and do not use dashes.
