abstract = {The functional efficacy of colocalized, linked protein
domains is dependent on linker flexibility and system
compaction. However, the detailed characterization of these
properties in aqueous solution presents an enduring
challenge. Here, we employ a novel, to our knowledge,
combination of complementary techniques, including
small-angle neutron scattering, neutron spin-echo
spectroscopy, and all-atom molecular dynamics and
coarse-grained simulation, to identify and characterize in
detail the structure and dynamics of a compact form of
mercuric ion reductase (MerA), an enzyme central to
bacterial mercury resistance. MerA possesses
metallochaperone-like N-terminal domains (NmerA) tethered to
its catalytic core domain by linkers. The NmerA domains are
found to interact principally through electrostatic
interactions with the core, leashed by the linkers so as to
subdiffuse on the surface over an area close to the core
C-terminal Hg(II)-binding cysteines. How this compact,
dynamical arrangement may facilitate delivery of Hg(II) from
NmerA to the core domain is discussed.},
