Examination of the amino acid composition of a newly isolated protein indicates the presence of ten lysines, five arginines and three methionines. When the protien is treated with cyanogen bromide, four peptides are obtained. When treated with trypsin, 15 peptides are obtained. What do these results suggest regarding the sequence of the protien? Please be as specific and detailed as possible.
Explain how you would carry out these two reactions and why you obtain the products you indicate
