The fact that you cannot find structures with NADH is because from the
crystallographic point of view, as you cannot see the hydrogens, then
both NAD+ and NADH are the same structure and are thus labeled as
"NAD" in a PDB. Therefore if you are looking for a NADH structure you
need to look for the structure of a NAD containing enzyme in the
reduced state.
NADH has the label "NAI" in the pdb, where as NAD+ is labelled "NAD".
NAD+ and NADH are also slightly different at the nicotinamide ring due
to the extra hydrogen.
