چکیده

Mechanical unfolding of the fourth domain of Distyostelium discoideum filamin (DDFLN4) was studied in detail using the C(alpha)-Go model. We show that unfolding pathways of this protein depend on the pulling speed. The agreement between theoretical and experimental results on the sequencing of unfolding events is achieved at low loading rates. The unfolding free energy landscape is also constructed using dependencies of unfolding forces on pulling speeds.

A structure-based model fails to probe the mechanical unfolding pathways of the titin I27 domain.

We discuss the use of a structure based Cα-Go model and Langevin dynamics to study in detail the mechanical properties and unfolding pathway of the titin I27 domain. We show that a simple Go-model does detect correctly the origin of the mechanical stability of this domain. The unfolding free energy landscape parameters x(u) and ΔG(‡), extracted from dependencies of unfolding forces on pulling s...

Mechanical unfolding of a beta-hairpin using molecular dynamics.

Single-molecule mechanical unfolding experiments have the potential to provide insights into the details of protein folding pathways. To investigate the relationship between force-extension unfolding curves and microscopic events, we performed molecular dynamics simulations of the mechanical unfolding of the C-terminal hairpin of protein G. We have studied the dependence of the unfolding pathwa...

Unbinding and unfolding of adhesion protein complexes through stretching: interplay between shear and tensile mechanical clamps Protein complexes in mechanical clamps

Using coarse-grained molecular dynamics simulations, we analyze mechanically induced dissociation and unfolding of the protein complex CD48-2B4. This heterodimer is an indispensable component of the immunological system: 2B4 is a receptor on natural killer cells whereas CD48 is expressed on surfaces of various immune cells. So far, its mechanostability has not been assessed either experimentall...

Direction-dependent mechanical unfolding and green fluorescent protein as a force sensor.

An Ising-like model of proteins is used to investigate the mechanical unfolding of the green fluorescent protein along different directions. When the protein is pulled from its ends, we recover the major and minor unfolding pathways observed in experiments. Upon varying the pulling direction, we find the correct order of magnitude and ranking of the unfolding forces. Exploiting the direction de...
