abstract = {The binding of the human nerve growth factor (NGF) protein
to tropomyosin receptor kinase A (TrkA) is associated with
Alzhemeir’s development. Owing to the large presence of
zinc(II) ions in the synaptic compartments, the zinc ions
might be bound to the complex in vivo. Here, we have
identified a putative zinc binding site using a combination
of computations and experiments. First, we have predicted
structural features of the NGF/TrkA complex in an aqueous
solution by molecular simulation. Metadynamics free energy
calculations suggest that these are very similar to those in
the X-ray structure. Here, the “crab” structure of the
NGF shape binds tightly to two TrkA “pincers”. Transient
conformations of the complex include both more extended and
more closed conformations. Interestingly, the latter
features facial histidines (His60 and His61) among the
N-terminal D1–D3 domains, each of which is a potential
binding region for biometals. This suggests the presence of
a four-His Zn binding site connecting the two chains. To
address this issue, we investigated the binding of a D1–D3
domains’ peptide mimic by stability constant and nuclear
magnetic resonance measurements, complemented by density
functional theory-based calculations. Taken together, these
establish unambiguously a four-His coordination of the metal
ion in the model systems, supporting the presence of our
postulated binding site in the NGF/TrkA complex.},
