Question

Use the table and ramachandran plot. List all of the regions in lysozyme that are likely to be part of an alpha helix.

(Consider a range of +/- 15° degrees relative to the ideal alpha helix phi/psi angles listed in the table under the Ramachandran plot in the “Rama_plot” supplemental file.)

Please explain and thank you for your help!

I updated the pictures, hopefully you can now see them better.

180 90 90 180 1800 90 90 180 (deg) Figure 8-7 The Ramachandran diagram. It shows the sterically allowed and ls angles for poly-L-alanine and was calculated using the van der Waals distances in Table 8-1. Regions of "normally allowed" and angles are shaded in blue, whereas green-shaded regions correspond to conformations having "outer limit" van der Waals distances. The conformation angles, dand l, of several secondary structures are indicated below: (deg) (deg) Secondary Structure Right-handed a helix (a) 47

Explanation / Answer

25th amino acid residue Leusine to 35th number residue Glutamate will make  alpha helix.

Threonine 41 and glutamate 42 can also a part of alpha helix.

Threonine 47, isoleusine 47, Arginine 61, proline 71 and glycine 71 can also make alpha helix.
