Apamine is a small monomeric peptide toxin present in the venom of the honeybee. It has the sequence: CNCKAPETALCARRCQQH (a) It is known that apamine does NOT react with iodoacetate. How many disulfide bonds are present? (b) Suppose trypsin cleavage gave two peptides. Where is (are) the S-S bond(s)? (Hints: If cut by trypsin, but still held together by a disulfide bond, count it as a single peptide. Also, do not count a single amino acid as a "peptide.")
