Biochemistry Help!

Consider the following: A hexapeptide contains equimolar amounts of met, ser, tyr, leu, asp and arg Cleavage of the hexapeptide with trypsin yielded two products: a pentapeptide and free ser Cleavage of the hexapeptide with CNBr yielded two product peptides. One was a dipeptide containing ser. Cleavage of the hexapeptide with chymotrypsin yielded two product peptides. One of these was a dipeptide containing leu Based on above information, what is the amino acid sequence of the hexapeptide? (Be careful: no partial credit on this problem.)

Explanation / Answer

met-leu-tyr-ser-asp-arg
