abstract = {We investigated the force-induced dissociation of single
specific bonds between protein A and immunoglobulin G. In
these experiments both proteins were tethered to microbeads.
Piconewton forces were applied by means of an ultrasoft
spring. Upon bond formation the thermal fluctuations of this
soft spring were reduced. This resulted in a sizeable
contribution to the free enthalpy of bonding. Including this
effect we calculated the relation between the lifetime of
bonds connecting both microbeads and the lifetime of the
bond between free molecules. We found that in the first case
the lifetime depended on the stiffness of the force probe.
Moreover, the lifetime was reduced by almost two orders of
magnitude. Both predictions were verified in our
experiments.},
