Work Step by Step
The sequences resulting from the first treatment,
asp-thr-ala-trp, gly-glu-ser-lys, trp-arg
The sequences resulting from the second treatment,
thr-ala-trp , gly-glu , ser-lys-trp-arg-asp
The largest peptide from the analysis is
ser-lys-trp-arg-asp
From the first set of analysis, Ser is preceded by gly-glu. So,
gly-glu-ser-lys-trp-arg-asp
From the first set of analysis, asp is followed by thr-ala-trp. So, the complete sequence is
gly-glu-ser-lys-trp-arg-asp-thr-ala-trp
