How molecular knots can pass through each other.

چکیده
We propose a mechanism in which two molecular knots pass through each other and swap positions along a polymer strand. Associated free energy barriers in our simulations only amount to a few kBT, which may enable the interchange of knots on a single DNA strand.

Tight knots in proteins: can they block the mitochondrial pores?
Proteins need to be unfolded when translocated through the pores in mitochondrial and other cellular membranes. Knotted proteins, however, might get stuck during this process since the diameter of the pore is smaller than the size of maximally tightened knot. In the present article, I briefly review the experimental and numerical studies of tight knots in proteins, with a particular emphasis on...
متن کاملThe tangled web of self-tying knots.
M athematician Leopold Kronecker stated “God created the integers, all else is the work of man,’’ alluding to the fact that the natural numbers most likely arose from physical counting, as in one’s fingers or goats in the pasture. Topology, however, is arguably a different creature altogether and may have had its own independent origins from the physical world in the ubiquitous knot—something t...
متن کاملConstructing parametric quadratic curves
Constructing a parametric spline curve to pass through a set of data points requires assigning a knot to each data point. In this paper we discuss the construction of parametric quadratic splines and present a method to assign knots to a set of planar data points. The assigned knots are invariant under a ne transformations of the data points, and can be used to construct a parametric quadratic ...
متن کاملEntropic Interactions between Two Knots on a Semiflexible Polymer
Two knots on a string can either be separated or intertwined, and may even pass through each other. At the microscopic scale, such transitions may occur spontaneously, driven by thermal fluctuations, and can be associated with a topological free energy barrier. In this manuscript, we study the respective location of a trefoil (31) and a figure-eight (41) knot on a semiflexible polymer, which is...
متن کاملOn Composite Twisted Unknots
Following Mathieu [Ma], Motegi [Mo] and others, we consider the class of possible composite twisted unknots as well as pairs of composite knots related by twisting. At most one composite knot can arise from a particular V -twisting of an unknot; moreover a twisting of the unknot cannot be composite if we have applied more than a single full twist. A pair of composite knots can be related throug...
