Webb3 mars 2009 · Knots observed in proteins are “open” knots, and so they differ from the mathematical definition of (closed) knots. Nonetheless, when both termini of the protein are located far enough from its entangled core, they usually can be unambiguously joined by an additional interval that transforms them to a closed loop.
