Query: Conformational transformations induced by the charge-curvature
  interaction   A simple phenomenological model for describing the conformational dynamics of
biological macromolecules via the nonlinearity-induced instabilities is
proposed. It is shown that the interaction between charges and bending degrees
of freedom of closed molecular aggregates may act as drivers giving impetus to
conformational dynamics of biopolymers. It is demonstrated that initially
circular aggregates may undergo transformation to polygonal shapes and possible
application to aggregates of bacteriochlorophyl a molecules is considered.
