Question
The carbon-nitrogen peptide bond is rigid, but rotation can
take place about the N-C and the Co-C bonds in a protein
(Co is the a carbon atom). These bond angles define the
conformation of the peptide chain.
Consider the Ramachandran plot to answer both questions.
Which observation most likely describes part of an
observed a helix?
p = +60°; y
+40°; many Gly residues
= -60°; y = −47°; many Ala residues
=
= -57°; y = −47°; many Pro residues
= -140°; y = +130°; many Val residues
p = -59°; y = +150°; many Ser residues
Which observations would not likely occur in a ẞ sheet?
p = +60°; y = +60°; many Gly residues
p = −57°; y = −49°; many Ala residues
= -120°; y = +120°; many Tyr residues
= -51°; y = +153°; many Gly and Pro residues
p = −139°; y = +135°; many Val residues
