Question

Hi, my professor asked me to develop a protein sequencing problem. Can check to see if I did it right?
Please make any corrections. I still trying to learn the material.
1. Pro, Gln, Tyr, Cys, Arg, Ser, Phe, Lys, Val, Met ( 10 blanks)
a. DFNB gives Gln
b. Carboxypeptidase gives Ser
c. Trypsin gives tetrapeptide with Ser, a dipeptide with Arg and a tetrapeptide with Gln, Phe, Lys, and Cys.
d. Chymotrypsin gives a tripeptide with Gln; and a dipeptide with Val; a tripeptide with Met; and Ser by itself

Ans? Gln-Cys-Phe-Lys-Pro-Arg-Tyr-Met-Val-Ser

2. Met, Asn, Gln, Asp, Lys, Val, Arg, Tyr, Trp, Glu (10 blanks)
a. DFNB gives Met
b. Carboxypeptidase gives Gln
c. Trypsin gives a tetrapeptide with Met, Tyr, Asn, Lys; gives Glu a hexapeptide and Met is by itself
d. Chymotrypsin gives a tripeptide with Met; a tripeptide with Gln, Asp, Arg, and a tetrapeptide that Val next to Asp
Ans? Met-Asn-Tyr-Lys-Gln-Trp-Val-Asp-Arg-Gln
