abstract = {Octopine dehydrogenase (OcDH) from the adductor muscle of
the great scallop, Pecten maximus, catalyzes the NADH
dependent, reductive condensation of L-arginine and pyruvate
to octopine, NAD(+), and water during escape swimming and/or
subsequent recovery. The structure of OcDH was recently
solved and a reaction mechanism was proposed which implied
an ordered binding of NADH, L-arginine and finally pyruvate.
Here, the order of substrate binding as well as the
underlying conformational changes were investigated by NMR
confirming the model derived from the crystal structures.
Furthermore, the crystal structure of the OcDH/NADH/agmatine
complex was determined which suggests a key role of the side
chain of L-arginine in protein cataylsis. Thus, the order of
substrate binding to OcDH as well as the molecular signals
involved in octopine formation can now be described in
molecular detail.},
