Determine the sequence of the hexapeptide on the basis of the following data. Note: when the sequence in not known, a comma separates the amino acids. Amino acid composition: (2R,A,S,V,Y) N-terminal analysis of the hexapeptide: A Trypsin digestion: (R,A,V) and (R,S,Y) Chymotrypsin digestion: (A, R, V, Y) and (R, S) V-R-Y-S-R-A A-V-R-Y-R-S A-V-R-Y-S-R V-R-Y-R-S-A
