Abstract:
We study the translocation of a flexible polymer through extended patterned pores using molecular dynamics (MD) simulations. We consider cylindrical and conical pore geometries that can be controlled by the angle of the pore apex α. We obtained the average translocation time ⟨τ⟩ for various chain lengths N and the length of the pores Lp for various values α and found that ⟨τ⟩ scales as ⟨τ⟩∼NγFLpNϕ, with exponents γ = 3.00 ± 0.05 and ϕ = 1.50 ± 0.05 for both patterned and unpatterned pores, respectively.

Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
