Question
Chapter 5, Problem 32CQ
Summary Introduction
To determine: The sequence of the intact peptide.
Concept introduction: Proteins are made up of one or more amino acids linked together to form a chain. The building blocks of the protein is called amino acid. Amino acids are termed as residues if they release a hydrogen ion from the
Given:
- Cleavage with cyanogen bromide (CNBr) yields three smaller peptides: Arg-Ala-Tyr-Gly-Asn, Leu-Phe-Met, Asp-Met.
- Cleavage with chymotrypsin yields three peptides: Met-Arg-Ala-Tyr, Asp-Met-Leu-Phe, Gly-Asn.
