Question
Polyglycine, a simple polypeptide, can form a helix with ?=?80? , ?=+150? . From the Ramachandran plot (see the figure on the left), describe this helix with respect to handedness.
Check all that apply.
Check all that apply.
It could be left-handed helix.
It could have 310 helix structure.
It could have parallel ? strands structure.
It could have ? helix structure.
It could have antiparallel ? strands structure.
It could have polypeptide II helix structure.
It could be right-handed helix.
Explanation / Answer
Polyglycine could have the following structures:
* It could have alpha-helix structure
* It could be left handed helix
* It could have antiparallel beta-strand structure (due the side chain composed only of H atoms)
