Trying to figure out this sequencing quesiton. Please explain how you would approach this and what the sequence would be at the end. Thank you

2. Determine the sequence of the 14-mer peptide given the following data: a. Amino acid composition: (4S, 2L, F, G, I, K, M, T, W, Y) b. ment of peptide with 1-fluoro-2,4-dinitro benzene followed by hydrolysis DNP-S

Solution

(a) 4 serine, 2 leucine, phenyalanine, glycine, isoleucine, lysine, methoinine, thereonine, tryptophan, tyrosine..

(g) 2 serine, leucine, tryptophan, phenyalanine, glycine, isoleucine, lysine, leucine, homoserine, thereonine, tyrosine

(e) Glycine, lysine, leucine, phenyalanine, isoleucine, tryptophan, thereonine, methoinine
