Protein Folding

[mdl24]

Hello,

In Roger Penrose's book, The Emperor's New Mind, it is asserted that certain
types of crystal formation may include non-local quantum effects. It occured
to me that perhaps quantum effects are involved in protein folding - it is
impossible for a protein to try every possible conformation sequentially so
perhaps several different conformations are attempted in paralell.

Is this at all possible?
