Work Step by Step
The sequences resulting from the first treatment,
trp-glu-val, gly-arg, ala-ser-phe-gly-asn-lys
The sequences resulting from the second treatment,
gly-asn-lys-trp, glu-val, gly-arg-ala-ser-phe
It is given that it is a 11 amino acid peptide.
The largest peptide from the analysis is
ala-ser-phe-gly-asn-lys.
From the second set of analysis, ala is preceded by gly-arg. So,
gly-arg-ala-ser-phe-gly-asn-lys.
From the second set of analysis, asn-lys is followed by trp. So, the complete sequence is
gly-arg-ala-ser-phe-gly-asn-lys-trp-glu-val
