Sequence-specific
binding of proteins to DNA is essential for accessing genetic
information. Here, we derive
a simple equation for target-site recognition, which uncovers a
previously unrecognized coupling between the macroscopic association and
dissociation rates of the searching protein. Importantly, this
relationship makes it possible to recover the relevant microscopic
rates from experimentally determined macroscopic ones. This post
contains kinetic data for the lac repressor and code to analyse and
interpret the data in light of this theory.
