I heard a concept that the [+,+] & [-,-] phi-psi angle combination (i.e. same sign) results into a curvature of the peptide backbone conducive for helix formation. Whereas a combination of [+,-] or [-,+] phi-psi (i.e. opposite signs) cancels out the curvature thus conducive for beta sheet formation. Tell me whether you agree with this above statement. If yes, could you provide me with some credible reference to back it up? Please.
Glad to have found this channel. Thank you Sir! You are awesome.
Thank you for this!!

Isn't left handed alpha helix first quadrant?
Sir I have a doubt how metal ions can dock
