Need help with the last 4 questions.
Thanks. iPad 6:17 PM 68%- 7) The following table gives the torsion angles and of hen egg white lysozyme for residues 24 73 of this 129-residue protein 14 pts TABLE 8-7 Torsion Angles (b. ) for Resides 24 to 73 of Hen Egg White Lysozyme Number (deg) (deg) 147 (deg) Gly -18 131 -115 -126 51 Thr 31 -107 GIn Phe -67 -126 -133 -100 -151 133 142 -142 -154 135 -122 121 70 71 -110 174 Gly 73 124 Source Imoto, T., Johnson, LN " North, A.CT.

Explanation / Answer

d) Probable identity of residue 54 is "Glycine". It has no beta carbon and side chain and appears throughout the area of Ramachandran plot.

e) The secondary structure of residues 56 - 68 is Beta sheets.

f) The secondary structure of residues 69 - 71 is Right handed alpha helix.

g) Additional information about charge distribution, hydrophobic interaction among alpha helix and beta sheets needs to be taken into account along with torsion angles for defining the 3-dimensional structure of a protein.
