A decapeptide which could resist burns was isolated from an endemic plant from Mt. Mayon. Deduce the amino acid sequence of the decapeptide given the following informations.
Mercaptoethanol gave two pentapeptides F1 and F2.
Chymotrypsin treatment of F1 releases S and a tetrapeptide (C,K,F,M) while F2 gave a dipeptide (M,S) and a tripeptide (C,F,K)
F1 when treated with CNBr released a free homoserine lactone and a tetrapeptide.
Trypsin treatment of F1 gave a tripeptide and a dipeptide.
F2 treated with carboxypeptidase released free M while with trypsin gave free K and a tetratpeptide.

Trp, and Val Reacting the native peptide with FDNB and then hydrolyzing released 2.4- dinitrophenylvaline. Brief incubation of the native peptide with carboxypeptidase yielded free Leu. Incubation with cyanogen bromide yielded two fragments: a tetrapeptide with composition Met, Phe, Ser, and Val, and a hexapeptide. The hexapeptide yielded 2.4- dinitrophenylglycine. Proteolytic cleavage by trypsin of the native peptide gave free Leu, a tripeptide,...
