TRANSLOCATION OF A PROTEIN-LIKE CHAIN THROUGH AN INTERACTING CHANNEL
The effect of channel-protein interaction on the translocation of a protein-like chain through a finite channel under certain electric field was studied by using dynamical Monte Carlo simulations. The interior behavior of chain conformation under different interactions was investigated
such as the number of monomers outside of channel

and the average energy

. It shows that with strong attractive interaction
the translocation is more difficult than moderate interaction. At the same time
the dependence of translocation time with different interactions shows that moderate repulsive interaction (
ε
cp
= 0.5) accelerates the translocation. Although the waiting time for successful translocation of
ε
cp
= 1.0 is the longest
the average translocation time is not very large. It is far smaller than that of
ε
cp
= -1.0. The probability distributions of translocation time p(
