Question

You have digested a small protein with two different proteases, each protease acting on the protein in separate reactions. These are the peptide fragments generated:

Trypsin:

IPVK: Ile-Pro-Val-Lys

ALEL: Ala-Leu-Glu-Leu

HRPGDR: His-Arg-Pro-Gly-Asp-Arg

FGADAEDGAMNK: Phe-Gly-Ala-Asp-Ala-Glu-Asp-Gly-Ala-Met-Asn-Lys

YLEFISECIIQVLQSK: Tyr-Leu-Glu-Phe-Ile-Ser-Glu-Cys-Ile-Ile-Gln-Val-Leu-Gln-Ser-Lys

Chymotrypsin: (Reaction conditions were used to maximize cutting to the C-terminal size of F, W, and Y.)

LEF: Leu-Glu-Phe

IPVKY: Ile-Pro-Val-Lys-Tyr

GADAEDGAMNKALEL: Gly-Ala-Asp-Ala-Glu-Asp-Gly-Ala-Met-Asn-Lys-Ala-Leu-Glu-Leu

ISECIIQVLQSKHRPGDRF: Ile-Ser-Glu-Cys-Ile-Ile-Gln-Val-Leu-Gln-Ser-Lys-His-Arg-Pro-Gly-Asp-Arg-Phe
