What types of primary structures destabilize helices?
Answer / kurt heller
the question may be in error
helices are atabilized by by hydrogen bonds between peptide
groups
some aminoacids like: gly, pro, ser do not like to be
inside a helix, because they break the hydrogenbonding
pattern within a helix
aminoacids like: thr, ile and val have beta-carbons which
restricts the way the sidechains sticking out from the
helix can pack together
the acid aminoacide: glu and asp prefre the N-teminal end,
because the helic is a dipole
the opposite is true for the basic aminoacids: arg and lys
the rest is mostly indifferent<, take a look at Chou and
Fasman statestics for aminoacids for helices
