Question: A 14-residue peptide, TRWVKVNGKWIKQA, in the context of a protein forms a ?-hairpin, consisting of two anti-parallel ?-strands connected by a turn. You have found that the amide nitrogen of arginine forms a hydrogen bond with the carbonyl oxygen of glutamine. Based on your finding, characterize the structure of the hairpin as follows:
(a) Draw schematically all the hydrogen bonds between the backbone atoms for this hairpin. Do not draw the side chains - just indicate what residues are connected by H-bonds. How many hydrogen bonds between the backbone atoms are present in the structure?(b) What residues are involved in the ? -turn?
